Review: A well rounded trackball - I have a Logitech M570, Logitech Trackman Marble, Adesso Trackball, Kensington Expert, and the Kensington Orbit with scroll ring. Trackball experiences are very subjective because our hands are all different shapes and sizes, and we use different techniques. In my experience the Kensington Orbit with scroll ring is the overall winner. With regard to performance, the Kensington Expert is the best. It is also two to three times the price of all the other trackballs listed. Additionally, the Expert is tilted at a steep angle toward the user. This can put your wrist in an awkward and painful position. The Logitech Trackman Marble and the Orbit are both tilted slighty away from the user, and this is very comfortable. The scroll ring on the Orbit is also much smoother than the scratchtastic Expert. The Logitech Trackman Marble is the most like the Orbit. The trackballs are the same size and have a similar form. The shape of the Marble is more comfortable overall and has two additional programmable buttons. The Orbit has somewhat less comfortable button placement, and lacks the extra buttons. The Orbit can be programmed to emulate a middle click by pressing both buttons. However, the Logitech does not have any scroll wheel or scroll ring. That's an automatic disqualification in my book. The Orbit wins by default. The Adesso Trackball gets a number of negative reviews, and rightfully so. It has the most useless button placement I have ever seen. However, it does have a much larger ball than the Orbit and Marble, has a higher resolution (800dpi), has a scroll wheel, and is in the same price range. With a couple of modifications and the use of arm rest (I use a thick text book), it is a truly fantastic trackball. However, out of the box the Orbit and the Marble leave the Adesso in the dust. The M570 is a thumb controlled trackball. Many people love them, while others abhor them. (I happen to have no preference, and use both) If you have a predilection for a fingertip controlled ball, the Orbit and other trackballs win this round. Otherwise, the M570 is a top notch device. While the other trackballs may best the Orbit in one way or the other, it scores well in all areas. It gets my recommendation as the best overall affordable trackball. The rundown Pros: -affordable -comfortable shape -smooth rolling ball -the best scrolling apparatus -a good size Cons: -no extra buttons -no dedicated middle click button -slightly awkward button placement Review: My daily driver for 9 years and counting - I have been using this model of mouse for over 9 years now (Edit: 15 years? Who's counting). I first got one of these in high school as a present from my dad, who uses this himself. It's gotten me through undergrad, master's, and a couple years of working. I love it so much. I've bought multiple ones to use at home, office, and a spare in case they ever discontinue it. Not one has failed so far. I have attached photos of how I position my hand on it: thumb on left button, index finger on ball, middle finger on wheel, and ring finger on right button. My pinky sits off to the side and doesn't operate the mouse at all. This is just how I use it, YMMV depending on your hand size and whatever you find most comfortable. I find that my pinky just isn't strong enough to do a lot of clicking without getting tired after a while. My index finger is the most dextrous finger, so it's good for precise operation of the track ball. I tried some of the other hand positions described in other reviews, and I found them uncomfortable and awkward, so it's a very personal thing. Play around with it to find what works best for you. I don't use the included wrist rest. I think it's more comfortable to rest my wrist directly on the desk, based on the slope angle of the mouse (probably because my hands are small). Again, YMMV. Pros (why I love this mouse): - Very comfortable and ergonomic for extended use (for me at least). My hand and wrist rest on it in a neutral position. - Track ball allows fast and precise movements. A traditional mouse depends on moving the entire forearm/wrist, which is slower and less precise. - Left-clicking with my thumb is easier than a standard mouse because it's a stronger finger than my index finger and doesn't get tired as easily. - Large scroll wheel is easy to operate. I can either scroll a tiny bit or fling it to scroll a lot, and I don't have to bend my finger as much as a traditional mouse scroll wheel requires. There's another model of Kensington track ball mouse that has a scroll wheel like this (the one with 4 buttons) but I find that one awkward to position my hand on. Cons (only minor annoyances for me): - Coworkers have no idea how to use it when they come to my computer to show me something. - Larger than a traditional mouse, doesn't fit in a standard laptop case. - The area under the ball gets gross pretty quickly and is hard to clean because it has a lot of nooks and crannies. I usually just clean off the three supports to make the ball move more freely, about every other week. - No software support for Linux or Chromebook, so you can't customize buttons with those operating systems. - No middle-click, but this may be emulated by your OS as simultaneously clicking left+right buttons. - Probably hard to game with this. I don't game, so this is not an issue for me. Edit (2026): Yup, I still use this mouse! I've acquired one of the newer wireless ones with the red ball (which otherwise works the same as this item) and that one works great too. Still have my original wired ones too. One of them had some issues a few years ago but I opened it up and cleaned out some gunk with alcohol and that fixed it. I will probably keep using these until I die, or until AI makes computer input devices obsolete. :) ## Features - Optical tracking technology provides precise cursor movement for superior accuracy so you can get where you want on the screen Quickly with less hand movement, improving productivity and efficiency; The blue 40mm ball has been specially designed with an absolute spherical, hard surface for precise tracking and control - Unique scroll Ring let you move up and down web pages or documents with ease; ambidextrous design works equally well for both right-handed and left-handed users - Detachable Wrist rest softly cushions and cradles the hand and wrist in an ergonomic position for pain-free productivity during extended periods of activity on the computer - Free downloadable KensingtonKonnect software provides a personalized experience, giving you the ability to assign a wide variety of program functions to each of the 2 buttons, as well as adjusting cursor and scrolling speeds - ChromeOS user can get HID functions for a trackball but will not be able to customize their device through KensingtonWorks. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002OOWB3O | | Additional Features | Ergonomic Design | | Antenna Location | Office | | Best Sellers Rank | #3 in Computer Trackballs | | Brand | Kensington | | Button Quantity | 2 | | Color | Black-Blue | | Compatible Devices | Personal Computer | | Connectivity Technology | Wired | | Customer Reviews | 4.3 out of 5 stars 7,608 Reviews | | Enclosure Material | Plastic | | Global Trade Identification Number | 00085896723370 | | Hand Orientation | Ambidextrous | | Hardware Platform | PC | | Item Dimensions L x W | 8"L x 6"W | | Item Weight | 10.4 ounces | | Manufacturer | Kensington | | Mfr Part Number | K72337US | | Minimum Required Operating System Version | ChromeOS 137 | | Model Name | Orbit with Scroll Ring | | Model Number | K72337US | | Movement Detection | Optical, Trackball | | Movement Detection Technology | Optical , Trackball | | Number of Batteries | 1 AA batteries required. | | Number of Buttons | 2 | | Operating System | mac os | | Pattern | Mouse | | Power Source | Corded Electric | | Range | 30.0 feet | | Special Feature | Ergonomic Design | | Style Name | wired usb | | UPC | 016622822432 777785625413 809385660928 803982770622 085896723370 | | Unit Count | 1 Count | | Warranty Description | 5 Year Warranty | ## Product Details - **Brand:** Kensington - **Color:** Black-Blue - **Connectivity Technology:** Wired - **Movement Detection Technology:** Optical, Trackball - **Special Feature:** Ergonomic Design ## Images ![Orbit Trackball Mouse with Scroll Ring (K72337US), 4 1/2X5 1/2X2" - Image 1](https://m.media-amazon.com/images/I/61-liuOVe0L.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: Do you have to put too much force on the left button while dragging? Do you have to put your hand in a awkward position to do it?** A: Hi, It's more in the pressure it takes to click the button (switch), Most of my mouses and trackballs have hair pin buttons meaning it doesn't take much pressure or finger muscles to click. This one is pronounced, it takes more pressure which over the period of time this adds up. I would send it back if it wasn't more trouble than it was worth to do so. I got it so I could train my left hand to use it. It sits in the closet now. **Q: How do the buttons feel when clicked? Are they too stiff? Do your thumb gets tired after a long period of use?** A: I was previously using a Logitech Marble Mouse trackball which has a much lighter click action than this unit. The overly heavy button springs are my only complaint with the Kensington. My thumb has gotten stronger in the time I have been using it, but long periods of game play do make it quite sore. In conclusion, I like the Logitech for game play and the Kensington for web browsing. Older users will have more trouble adjusting than younger ones. **Q: Does it have a scroll click (middle click)?** A: With πŸ’©KensingtonWorks 3.1.2 for Windows 10, in Firefox, "Middle Click" does not work for ... - "Right Mouse Button" with "Alt", "Shift", "Ctrl"; - "Left Mouse Button" with "Alt", "Shift"; - Assigning both button being clicked to be recognized as "Middle Click" is a game of chance. "Ctrl" + "Left Mouse Button" works as "Middle Click" without help "KensingtonWorks" software **Q: How long is the cord on the Kensington Orbit Trackball?** A: I did not measure it, but my guess is that it is around four feet long. I got the trackball for health reasons (wrist, carpal tunnel issues). So I had never even taken the plastic twist off the trackball until you asked the question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A well rounded trackball *by S***E on June 7, 2013* I have a Logitech M570, Logitech Trackman Marble, Adesso Trackball, Kensington Expert, and the Kensington Orbit with scroll ring.

This isn't quite comfortable as my favorite little track mouse which is no longer made. However, Kensington includes a really nice little ergonomic pad that attaches to the back of the body of the mouse. That helps immensely. The track ball moves really freely and feels very nice and easy to manipulate. The left click is slightly weird as when I utilize that ergo pad, my reach isn't quite perfect for the left side of the unit. Overall, this looks and feels like a good quality trackball. I'm pleased with my purchase. Edit to add: I just purchased a second one to use with my other PC. I miss the old track marble (side ball) but this is a very decent mouse, especially for the money ## Frequently Bought Together - Kensington Orbit Trackball Mouse with Scroll Ring (K72337US), 4 1/2X5 1/2X2" - Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring (K72352US),Black - Kensington Orbit Trackball Mouse (K64327F), Silver/Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/437240-orbit-trackball-mouse-with-scroll-ring-k72337us-4-1-2x5](https://www.desertcart.no/products/437240-orbit-trackball-mouse-with-scroll-ring-k72337us-4-1-2x5) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
