Good quality, 7 you can use, 3 are basically watch screw size.

Very nice screwdrivers. They seem to hold up under a decent amount of torque.

I just received these today. They seem to be decent quality. Time will tell if that is the case. I had to knock off one star because of the graphics on the handle. In the Amazon product photo, the sizes are clearly marked in black. On the set I received, the sizes are marked in light gray against a gray background. This is not a good idea when you are trying to quickly find the size you need. I used a fine point marker to make the sizes easier to read.

I came across some fasteners that were square drive. I had to improvise means to get them out. These were inexpensive to buy, so I had them for the next time.

Really good quality tool.

I haven't used them yet, but they seem to be a very nice set of tools.

DO NOT BUY!!! Doesn't fit anything! I purchased these hex allan drivers to fit the small Metric bolts that I purchased a while back and they do not fit the 3mm to 6mm bolts. One of the drivers was bent on the end from someone trying to make it work meaning it was used.I'd give this no stars if I could.It also doesn't fit my R/C car's hardware either. Cheap China junk.This review is for the Hex Allen Wrench Screwdriver Set (10 Pack in Precision & Standard Metric Sizes 0.9mm 1.27mm 1.3mm 1.5mm 2.0mm 2.5mm 3.0mm, 4.0mm, 5.0mm, & 6mm) - Perfect for RC Cars, Quadcopters, & Helicopters.
