I checked this before giving it to my nephews to make sure all of the pieces were there and I have to say I was very disappointed when I opened it. Unfortunately, by the time it arrived I didn't have time to return it and wait for a different toy to be delivered.
While I originally thought that the foldable structure would have been a good thing, it was actually quite flimsy. It's not the easiest structure for a child to assemble them self so the help of an adult is probably necessary; or was in our case. I don't think it will last very long before breaking.
It has 4 snap type clips to keep it shut when the child is using it as a carry case, however these aren't properly attached and just fall off. This is far from ideal as a children's toy as they are prone to becoming lost; in which case you can no longer lock the case.
For the price I was expecting a little more, but it is basically a box with 4 tools. My nephews enjoyed having extra tools but weren't really bothered by the workbench. Also you can't actually close the top case after playing. You have to unscrew and disassemble parts first which isn't ideal for parents, although the lack of parts provided mean that there isn't a large amount to disassemble.
I wouldn't recommend buying this.
