Review on ROKR DIY Wooden Puzzle Self Assembly by Yuan Walsh

This is a wonderful puzzle that will make a very pretty item for your robe/window decorations. Laser cut sheet metal is generally easy to machine, but occasionally a tight fit will occur when parts are assembled (note: this is all a friction fit - no glue is used). In this case, be careful not to damage the part (although it has a large selection of spares, just in case). Starting and driving is especially fun for the grandchildren because they can see the inner workings in motion. Assembly was pretty easy - just follow the instructions and take your time. A word of warning though - try to mount the gear assemblies as straight as possible - a little wobble won't hurt but some of them don't have much play. Originally bought as a present for an uncle but after receiving the set it looked so fun it became a set for ME (he will get his later). Very worth buying.
