The assembly of the plastic box is a pain. I don't know why they would use nuts and bolts to attach a plastic plate perpendicular to another. It takes four hands and some skill to assemble. When I was done the lid sat ajar, so I had to make a few adjustments. It stays together well enough, but does seem a little flimsy. When the arm retracted it would bounce against the switch in the bottom flexing the plastic piece that the motor is attached to. I fixed this by bending the metal tab on the switch up, so that the motor turns off sooner. The instructions are not a good step by step method. I found it easier to do things in a different order and there were a few things I had to guess at. It doesn't use much power, I suspect it will be a long time before I need to put new batteries in it. I am satisfied with the quality. I did have to use a utility knife to clean up the edge of one panel. I assembled this in a little over an hour on a day that I was stuck at home sick. If you have the tools and like a challenge I would recommend this kit. Some patience is required.
Tools used: jeweler's screwdriver set, needle nosed pliers, soldering iron, solder, utility knife, wire strippers (small)
I purchased a similar one from a different website and after assembly it worked great until one of my children dropped it.
The printed instructions were of very low quality and are not in color.
I looked up the directions on the company's web site and although they were in color the images were of very low resolution.
Switch broke in half after soldering it to circuit board. Threw it away at that point.
Everyone I show it to is REALLY hesitant to flip the switch thinking its going to explode, shock them, or worse. But once I get them to turn it on the smiles and laughs it creates are great.
The actual box is much smaller than I was expecting, and the assembly didn't come together as well as we'd hoped. The pieces are kind of loose. That being said, it is a Most Useless Machine, it does work, and it is definitely fun.
Is this worth 40$? Probably closer to 20$, given the lower quality of the materials, the size, and also the awkward assembly that is required.
EDIT: My friends cat played with this a bit. I'm guessing it fell, but part of it chipped off already. He has had it for about a week or week and a half. Yeah. If I could change my score, I'd give this 2/5 stars. Oh. Apparently I can change the stars.

I was aware of this before I made this purchase, and I'm an electronics enthusiast, so I have all of these tools plus a lot more on-hand. I read some previous bad reviews where people were complaining about needing the extra tools, but it states in the description that these are necessary and not included. I bought this for my kids (all under the age of 5), and they love this thing! Once again, please be aware that extra tools are needed to put this together. I really don't think it's fair that this is getting bad reviews because people aren't reading the details of this product.
