Lift Coaster

I was sure I had been foolish to buy this kit. Why? Because I am nearly 89 years old and have the infirnmities to be expected for those at my age. Because of the complexity of the kit and I did my best to be especially patient and careful. Even with that, because of my clumsiness and temporary lack of care and patience I broke 5 little pieces during the assembly. it's a good thing they all were wooden, because with tiny applications of wood glue I was able to repair them and use them. As a bit of care and a whole lot of luck would have it, I completed the assembly and, with only a correction for a forgotten part and one for a misaligned one, everything worked! That surprised and shocked my friend (and me, too). The precision of the laser cut parts amazed me. The instructions were, by and large, very clear and understandable, although in a couple of places the orientation of the pieces was not clear to me. All in all I was very pleased with the kit.

I have bought 5 of these for gifts. For people who are mechanically inclined and like to tinker and build things. Every single one has been a smashing success! Every recipient has loved the assembly and now has a cherished product to share and tinker with. I received reports that there were extras of a few pieces that might have been prone to breakage, but none of the extras were needed because none of the first attempt pieces broke. There is also enough uncut wood to cut your own custom pieces if needed. Perfect working order after assembly on every single style of this brand. I will not trust another brand but this one I can trust completely. And so can you. Great designs, great gifts. Go for it. Please Click the helpful button if this review was helpful to you.

Fun filled hours. Worked like promised. Any Puzzle people want an upgrade from one dimension to 3.

The design is ingenious. The build is not easy, many of the pieces are hard to put together and some are in odd positions. The ladder is hard and needs a lot of fine tuning to get it to work. I would recommend this to those who want a challenge

Puzzle went together well. Wording could have had been better describing some of the install components.

This is our third Rokr model and we love them all! We have two marble runs and the movie projector. These models are only held together by friction and don't require glue, yet they are very durable once completed. My 4 year old toddler has been playing with our first marble run model for two months and it's still going strong, although we encourage him to be gentle. I would not recommend assembly for little ones. The box suggest ages of 14+ and I agree. Some pieces require a decent amount of pressure to assemble as well as an intuition of the correct amount of pressure to apply. The connecting pieces are mostly thin wood so you could break them if not careful. I only broke a single piece across all three models but I could have easily broken a few more. Luckily, the company includes a few extra pieces of the parts that are easy to break or lose. In summary, these are a great buy for people who like functional models.

The tiny wood pieces are hard to pop out with breaking. Nice idea, bad design. No more wood ones for us!.

Great little puzzle/machine thing! This was a surprise for my husband cause he was bored at home all the time. It took a week to convince him to put it together, but once he started, he didn’t stop. It took him a few hours, maybe four or five at a leisurely pace. It was not very difficult, just need to pay close attention. The instructions were very clear, even had videos to watch, but he didn’t need them. A couple of the really tiny pieces broke trying to get them out of the board, but there were extra. Had to glue a couple pieces to keep them in the right spot. Worked very well after putting together, minor adjustments to stop the balls from jamming or falling out, but no major issues. Will buy another!

I just love these puzzles. I now have 3 of them and they are easy to build and fun and relaxing to play with.

Same as the first ROKR puzzle I did, packaged well and all the pieces were easy to pop out and assemble. Once concern with the way one piece is built with 3 little wood screws that go into opposite sides staying put, but once the built piece was snapped to the main board, it worked flawlessly. The arm that works the elevator is pretty cool to watch -- I've had 2 of these this Christmas and will consider getting a 3rd in another month or so -- great fun to assemble and end product is a neat showpiece! Highly Recommended!!!

Just finished the marble run, works just fine, enjoyed the challenge. I would suggest using a lite silicone grease as I think it works better then the wax. I build RC cars and trucks (have 27 of them) most kits come with some of it I used it sparingly it helps everything work better. Now onto the airship, got two at the same time would recommend to any one who enjoys a challenge will defanatly be buying more of them. Thanks

This model kit's tough to rate because it really depends on the type of experience you're seeking. I wanted a challenging experience for a clever kid. I knew, going in, that the age recommendation was 14 and up, and therefore, figured that with an adult's assistance (i.e. me), this project would be doable for someone a bit younger than the recommended age. Plus side: I have no regrets purchasing this kit. It was a fun and rewarding experience, and the end-product looks and works great. The clever kid loves it. Potential downside: I did find some of the tabs/slots to be extremely tight fits. Particularly difficult were parts that required joining multiple tabs/slots together and not knowing which slot was causing resistance. Pressing too hard might cause the layers of the wood to split. I happened to have a very slender filing tool that was the perfect size to shave off a bit of material here and there to facilitate a tight fit. At one point, I spent about 45 minutes joining, taking apart, filing, and repeating several times, before finally getting a critical structure to fit the base snugly. In summary, at least in my experience, it took some problem-solving and persistence to get this project done correctly. I watched a video of a guy putting the pieces with the ease of snapping Lego bricks together. That was not my experience. It required patience, dexterity, and a bit of creativity when dexterity was not enough.

Put this together while prepping for night shift. My nieces love playing with it every time they come over. Some pieces broke (either very small or because of my gorilla fingers) glued some things to prevent them from pulling away.
