UGEARS Wooden 3D Puzzles for Adults Aero Clock - Mechanical Puzzles for Adults, Wall 3D Clock Puzzle with Pendulum Model Kit - DIY Miniature Kit Crafts Gift for Birthday - 320 Pcs

This is the first time I’ve built one of these wooden models, and I gotta say it was super fun. Instructions were pretty clear for the most part and the end result feels like a solid mechanism. Didn’t break anything and got all the strings set up without too much trouble. It looks great, especially when it’s in operation. All that said, don’t expect it to work smoothly without putting in some extra effort to fine tune it. It’s super important to sand all the places that are indicated in the instructions, as well as any gear faces that may pass against the static supports. Especially important to sand the pendulum and escapement gear. The wax included in the kit is tricky to apply properly to the gears, so I got some candles from the dollar store and applied melted wax with a paint brush. That took a bit of time but overall it was enjoyable. I’ve spent a bit of time trying to break the clock in, and so far I’ve been able to get it to go for about 15 minutes before I need to give it a slight nudge. It’s improving quickly with more use though, so I’m feeling optimistic about it breaking the hour mark by the end of the week. Edit: 1 day later and it’s going for more than an hour now at a time now. Didn’t do anything except keep nudging it along to break in the mechanisms. I’d gladly build more of these models if I had the space for it!

Heel mooi. Wel voorzichtig ermee zijn. Ben er druk mee. Fijne tijdsbesteding. Hoge kwaliteit en duidelijke omschrijving. Prima product.

I don't do reviews, but in the case of the Ugears aero clock I just had to make an exception. The design and construction of this kit is definitely on another level. You get what you pay for in life. The build quality is of this kit is at the highest level. All I would say to would be buyers is take your time. Yes you could probably have it all together in a far less time than the 11 hours indicated by Ugears, but the result would certainly not be a working clock. Care and attention to detail are required. Sand all rough edges and pay particular attention to those parts with mating surfaces. Anything that rubs against or contacts with another part benefits from more attention when sanding and waxing. The smoother the better. The instructions are excellent, but in my case I had some difficulty in understanding the cord winding. Youtube did however quickly solve my problem. The end result is fantastic. Visually a work of art. A work of art that actually keeps good time and a pleasure to watch as the hour sees the balloon quickly descend from its slow rise over the hour. Personally I would not consider this kit as complex. Not for a child that wants quick results, more suited to teenagers and budding teenage adults who want to spend time creating something to be proud of. If you take your time and follow the instructions carefully you will love what Ugears have helped you create. Looking foward to my next Ugears kit. Have made many hints to Santa

I've built quite a few laser cut wood kits (marble races, clock, toys, etc), and this is the best so far. It was a real pleasure to build. The instructions are excellent. After a bit of fine tuning the clock keeps pretty accurate time, with run times of about 19 hours before I need to reset the weight. The wax stick that comes with the kit is not great (and is very small). Instead of hard wax, I used soft furniture wax, which was great for waxing the teeth of all the gears. The one small drawback with the clock is the setup of the faces. They're not easily read from a distance. I've set up 15 minute markers behind the balloon, which makes a fun (but not very accurate) way to read the time from further away. Further note: I have modified the string for the weight, and am now getting run times of 21 hours.
