7-Piece Set Hex Key Wrenches (0.7~3mm)

Pros: The main reason I've bought them was the need to screw down a loose screw in sku.65387. Since the screw is 0.9 mm wide I had a lot of problems finding a set that would contain such a small hex key. DX proved to be the best source to look for those. The main pro, and probably the main reason why are people looking for those, is their size - you got to have a lot of luck to come across a hex key sized 0.7 mm - and you have it right here. They come well-organised and packed.

Cons: The quality of the material is questionable - they seem to prove really well, but you have to be extremely careful with the small ones - due to their slim build it's more than just easy to snap them or at least bend.

Other: A really helpful and handy set if you are in need of operating with very small screws. Obviously, you won't find much use of them if you're not dealing with uncommon screw sizes, as it doesn't contain the more popular sizes like 5 mm for example. Despite that, you can't go wrong with buying that set - it will save you a lot of frustration in the future if you're stuck with a small screw.
