This is a very fun kit and works rather well. I have two complaints, the pictures show proper length screws, the screws that came in my kit were too long. It makes the project look a bit unprofessional. If you have an assortment of small metric screws, as I do, you can replace the long screws with the proper length screws. I used hex cap head screws because the crosshead screws tend to strip. I think black screws look more high-tech. The laser-cut parts are nice, however, the 3-D printed components are a little rough. The holes can be a bit tight on the base of the parts, To avoid problems starting the screws on these holes, you can run the screw in from the opposite side, and then you easily start the screw from the other side. For best performance, tighten the screws on the moving parts snug then back the screws off a half turn. This will allow the parts to move freely without a lot of "wobble." With the exception of the shortfalls mentioned above, I recommend this kit. For the price it is good.
