Look for the 2011 or later models on Amazon, the 2011 and 2013 are selling for less than this older model. Mechanically equivalent but with some updates. My review appears on the 2011 model.

Build quality is less than I was expecting. The case is pretty worthless. It does the job, as long as you aren't expecting too much. Obviously, if you were going to be using these much, I would recommend going with a better brand. If you just want them for the once a year project to assemble a bed/desk/bicycle etc, it should work for you. It's only a few months since I got this, and I've already replaced it with a higher quality and more comprehensive collection of sockets.
