I have not used them like crazy yet but after a few uses they appear to be pretty darn good. I am kind of surprised for how cheap / inexpensive they were.

The box is not the one pictured I bought this as a gift. I have an older set that used the box in the picture. It was a cheap box but it was sturdy and it worked. The box this comes with was bent out of shape when it arrived, and the latch did not work. The internal parts are hinged with screws and single nuts (nothing to keep the nuts from coming loose). One of the screws was cross threaded. I had to replace all the screws & nuts with new ones and I used lock nuts to keep it from falling apart.The drills in the box I got appeared to be straight. A bunch had fallen out of their holes, and at least one escaped the package it was shipped in since the set was missing a drill. Having read the reviews of other kits, I measured all of the drills. Some measured correctly, some measured up to 2 mils small, and at least one of the small numbered drills was duplicated. The machining of the drills was ok, but not great. at least on of the drills had a corner chipped off, a couple I looked at had asymmetric faces, and often it looked like the grinding wheel used for sharpening needed to be dressed. My guess is that these are factory seconds.

I bought 2 of these. When I recieved them both boxes were open in the box with many of the bits, expecially the smaller ones, scattered in the bottom. The small bits naturally don't have sizing printed on the. What a mess. We have not used the bits a lot yet so time will tell on their quality. Naturally the small ones like to snap.. We seem to abuse things here...

I have not used any of the drill bits yet bit I can tell you that I did not get the drill index box that was pictured in the ad. The box I got was a piece of junk and I could not even close it. So I ended up buying a good Huot Index box for $40. I will write another review on the drill bits once I get a chance to use them

Cuts Stainless Steel very nicely. Just what I was looking for.. Quick delivery Price was competitive. Just make sure you use lots of coolant.
