TM527 model

This model was the 3rd "under $100" TPMS system that I purchased for my 30' travel trailer with tandem axle. (The 1st 2, Brand X models just didn't work well at all. Wish I had bought this system first. Likes: - works as described, I can monitor tire pressure and tire temperature as well. - BIG screen fonts, easy to read - adjustable brightness levels - sturdy base mount - sensor battery life seems to be good. (original batteries now in 2nd year of use) - accurate information - quick tap on the receiver and you can view the tire temps. - alarm system for pressure and temperatures - long power cable. I can plug into the cig 12v in the backseat of truck, run the cable between the seats and snake it up the dash to the display. Nice and neat, keeps down the "cable clutter" in the cab. Dislikes: - DC hookup only, need cig lighter plug-in. - can be quirky. Occasionally need to unscrew/rescrew a sensor to get it to connect to receiver (sometimes I'll get 3 sensors reading immediately and the 4th will connect and read maybe 5 minutes down the road) Overall this has been a good product. We traveled about 5k miles last year with this unit. I have the 15" Goodyear Endurance tires at 80lbs. Provides confidence to run down the highway with your tires showing about 83lbs after they warm up at highway speeds. My goal is to give myself some advance warning if a tire is about to go. Even still, I'll do a walkaround at stops to check things out. After a trip, I disconnect the sensors and put them in a little bag until the next journey. I also put the little black caps back on the Shrader valves to keep everything clean. Edit: Oct 2024. Still working great. I also use 2 sensors (Left Front/Right Front) on a boat trailer. I set the "psi alarm" to 60psi when running the trailer. Trailer tires max psi is 50psi so I run them at 45. BE SURE to unscrew them before launching - they do come with little covers (I don't use them) but I'm not sure if they are 100% waterproof. I've swapped out the CR1632 batteries a couple of time now. The set comes with a little clamshell tool to easily swap the batteries. Again, very pleased with this product!

I had a system from Walmart that worked but was pretty unreliable. It also was hard to read as the screen was the size of a quarter. Then I got this one. I glued a piece of Velcro to my dash, the other piece to the back of the device. The pivoting holder given with this item was useless. I could not get it to work for me, it came loose everytime. It was almost like it belonged to a different device? But the Velcro works nicely so it's no issue due to how light this display is. As for the device itself, how can I not give 5 stars? Works like clockwork. It updates consistently and I have checked the pressure in the tires, compared it to the readings and it is spot on accurate. The display is easy to read. I never have a "dropped" sensor reading, which was the problem with the Walmart device. Excellent quality. Thank you Update June 2020: The system has identified several leaks in my tires, one was especially dangerous as the hole was in the wall and unrepairable. More recently, it let me know about a battery issue in one of the sensors. It alerted me to low battery, when in fact the battery had corrosion from probably water entering the sensor from a power wash. Replaced the battery and all is back to normal. It really is a great system, I can't imagine it being any better other than mounting options. Update December 2020: Still going strong. I was loading my vehicle at work recently only to hear this annoying alarm noise, of which I ignored. I had music playing with the key in accessory. Come to find out the tire monitoring system was trying to warn me of a low battery reading for my car itself 🤣 Battery totally dead, but hey, it tried to tell me. FYI, the battery was 2 1/2 years old and needed to be replaced. Also, I have discovered if you want to check tire pressure before moving the vehicle just turn the key to accessory, screw off the sensor from the tire, wait for the system to send out a dropped sensor warning, then screw it back in. The reading on the screen for that tire should be accurate. Update June 2022: System is perfect. It never misses a beat! Update July 2024: Still going strong. The only problem is when the batteries die it takes a long time for the system to recognize a new battery, but never has it stopped giving me tire pressure. Pretty amazing! August 2026: Never misses a beat!

Greetings I bought this item because my truck does not have a tire sensor system, The installation was easy and the tire sensor that fit over the valve stem were easy to install. The sensor was +/- 1 off which was good and had no issues with tire sensors. The suction cup on the monitor could be better. The cup would loose its suction and fall off. This happened numerous times. The monitor would hit my dash and luckily nothing broke those times. Today the suction cup lost its suction and fell, but this time it landed on the USB that connects to the monitor and cause it to break off from the mother board. I emailed the seller regarding a replacement. I will Update as soon as I get a response. 10/20/22 The seller sent me a replacement unit and I installed it. Works just fine. I also installed adhesive wire clips to secure the wires and also to keep the suction from hitting the dash. I had to use the new sensors that came with the unit. Customer service was outstanding and I do recommend the product. For those who do not have a tire sensor system, this product is great.

I purchased this device for my 32-foot travel trailer, and it has proven to be an excellent investment. Last year, I experienced two blowouts while traveling—one of which I wasn't even aware of until I stopped and discovered significant damage to my trailer. Had I been using this device, I likely could have avoided the costly repairs. This device monitors both air pressure and temperature, which are crucial factors when towing. Installation was straightforward: I mounted the monitor on the windshield, plugged it in, and it immediately connected to the tires. During our first trip using the monitor, we noticed the alarm went off the next morning after the air had cooled overnight, indicating low pressure in two tires. However, once we drove a mile and the tires warmed up, the pressure stabilized. I'm grateful the monitor alerted me—low tire pressure can easily lead to a blowout, especially when carrying a heavy load. I recommend following the instructions, which note that you need to start driving to obtain accurate readings. I suspect that those who experience issues may not be moving their vehicles as instructed. Given its reliable connection to the tires on my 32-foot trailer, I believe this device would have no trouble connecting to a car or truck. Overall, I'm very pleased with this purchase—it’s an affordable and valuable tool. Updated- make sure you don’t have old valve stems. Could cause some pressure on the valve stems. Places don’t replace the stems when you get new tires unless you request. Still use every time I tow the camper. Update: after a period of use the extra weight puts pressure on valve stems and causes a leak. I purchased the bolt on valve stems and had installed. Now there is no stem movement so no leak.

I don't leave reviews until I have used the product, I don't just open the product and leave a review stating that the item came well packaged and we'll see. What good is that review! Ordered this last year to use on our 21 ft. travel trailer. We used it on one trip of about 200 miles at the end of the season. Easy to install, just follow the instructions. Worked as per the instructions indicated at first. You had to be moving for the readings to display. Never had all four tires displaying at the same time but briefly. Accuracy seemed to be close when it did display. Sometimes only one tire displayed, sometimes two, three and sometimes none. There was nothing to cause any interference with the receiver or the pressure sensors. Per some of the reviews, maybe the batteries were old and weak. So this year I ordered new Duracell batteries at a cost of 20 more bucks. After all I was outside the return window and I needed it to work. Well today just got home from a 500 mile trip. Guess what! Same exact thing! The moral of the story is the same as always, you get exactly what you pay for. Especially from China! This product is a piece of Junk! Stay clear and don't buy it. Save yourself the grief. Spend the money and get a good safe tpms.

Update 12/12/20: Customer support reached out to me and sent a replacement unit, standing behind their product. I was thoroughly impressed with both the desire to make me happy and the speed of which they worked to resolve my issue. Replacement unit arrived and worked like a champ right out of the box. No issues / no hassle, just clear and concise tire pressure and battery voltage readout. The display unit is compact and has multiple mounting options. Changed my review to 5 stars, would definitely purchase again for second vehicle! Highly recommend this unit if your car like mine does not have an individual tire psi reading...especially with the winter months upon us. No luck with this purchase, these tire sensors did not work out of the box. The front two registered fine, the rear read 25 psi as soon as I installed and drove. I made a point to drive a decent distance above 45mph. Trouble shooting, I swapped the rear and front sensor and the issue followed the sensor to the front tire, reading 25psi where it had previously read 39 psi. Product website was no help either. Wanted to like these but looking elsewhere.

UPDATE: After a month of my original review I’ve realized why this things wasn’t working, the signal from my rear camera was causing interference and preventing this unit from working properly. I’ve since moved the display to a corner of my windshield and so far it has solved the issue. I’m still only giving this system a 3 stars as it shouldn’t interfere with other devices if it was built with quality components. I will still keep an eye on my next trip in a couple of weeks and update if necessary, but as for now other than the hassle of finding a “proper” location, the unit it’s doing it’s job. It worked while I was parked at the house and for the first 5 minutes of the 1800 miles trip… What a joke this thing is, i really had high hopes for this sensors as they had lot of good reviews but in my case the damn things where more an annoyance than anything. “Tire pressure monitor my ass” ALL this thing did throughout my entire trip was: giving me the truck’s voltage while driving, all sensor signals went out as soon as I hit the highway and didn’t even come back when I stop for fuel or to rest. So I will NOT recommend this garbage to anyone looking to be safe on the road while towing your TT. On a positive note: if all you want is the voltage of your alternator, this little gadget is for you. But I wouldn’t spend $70 on this thing just for that. Keep researching and take your money somewhere else.

First of all, they worked great, we’ve had three blown tires on our travel trailer and these give us peace of mind, that we can monitor the heat and pressure. That said, we’ve had no blow outs with them so I can’t say for sure if they would have detected the previous blow outs beforehand and prevented them. As for installing them, the instructions were missing some crucial information that I had to find actually here on the Amazon description, and it took a lot longer than it should have and would have, had the instructions been up to par. The install was just “snap and go,” but to get them to be accurately read by the monitor was the problem. Also, when we drive, both driver side monitors will must stop reading and the monitor will go blank. After a while they come back. Not sure what’s up with that.

L'installation comporte plusieurs pièces dont leur installation se retrouve sur divers petits manuels : tel que le recouvrement protecteur en caoutchouc, le capteur ou l'afficheur. Mais, ça n'enlève rien au produit, car une fois installé et programmé (limites haute et basse) l'afficheur fonctionne très bien.

Works just ok . Always issue with connectivity on all 4 trailer tires at same time

My first set purchased in 2022 was good, NOT the second set purchased on Jan 23 2023 in Canada. All the sensors got stucked from this recent purchase, can't taken off when changing tires a few days ago (the first set is still good and no problem taken off). Warning: contacted seller with no resolution and not helpful at all (they asked me to contact manufacturer but I can't even find the manufacturer's contact information in the user manual's last page as described on the description page on Amazon). Good customer service is important! I purchased 2 sets from you...

Unit worked fine for a few trips, gave the occasional false alarm. This trip it started beeping and showing low tire pressures when the tires were fine. Now it won’t read anything at all. Tried plugging and unplugging and resetting parameters but it still won’t read anything but battery voltage.

Bought for a trailer, doesn't work. Does not even have the range to monitor the trucks tires.
