Review on High-Quality 30-Piece Hex Key Allen Wrench Set - SAE and Metric Assortment, L Shape, Chrome Vanadium Steel, with Precise and Chamfered Tips. Sizes Include SAE 0.028 - 3/8 inch and Metric 0.7 - 10 mm. Comes in a Convenient Storage Case. by Ben Demers

Considering the price I would say that the price - money is pretty good. There are sizes in this set that I don't think I'll even need, but it's always good to be prepared. I had to use several different screws a few times and can't comment on durability as I didn't really have to loosen any of the very tight screws. The last time I had a set of allen keys that seemed to be the same color and material, I had to loosen a screw that was very tight and broke off on both sides fairly quickly. I have more faith in them than this one because the other one was very cheap and from Walmart. It's probably about the same price per piece, but I think they'll work a lot better. I'll definitely update my review as I always do when something unfortunate happens to them, but overall this set is great.
