Adequate but not quality
Like another recent reviewer wrote, these will work for their intended purpose, adequately. There is almost no bevel on the guide to better facilitate lining up in the hinge or screw hole for drilling more accurately. The materials seem cheap, but again, adequate. The box they came in was broken on deliver although the shipping package was well padded from Amazon so the broken plastic box was probably from the initial build. The bits were supposed to be separated in a foam cutout but the cutout was so thin and cheap that it was crushed and useless already.They will work for my simple woodworking and hobby crafting.

pretty much useless
The centering sleeves had little to no taper on the points. So, the do not easily find the hardware hole that you are trying to center. The smaller sizes had centering sleeves larger than the screw head, so, they would in no way find the hole location. Pretty well renders these to be useless.Even the centering punch they supplied was useless. Dull point and no centering sleeve. Why would I want it?

These Bits are Garbage
I would not recommend these bits. The spring loaded sleeve that is supposed to center the bit in a hole is flimsy and does not accurately center the bit. It wobbles and fits very loosely within the Chanel in which it rides. The Steve also gets stuck in the up right position, requiring you to pull it down between uses. The bits also do not protrude far enough to make a suitable pilot hole. I'm going to keep searching for a quality set of bits, since I need to use them often in my work.

Cheap material design
Very cheap design, one broke the very first time I used it.

Not the best but good to have around in a pinch.
The springs and circ clips are thin and flimsy inside. The first one I used broke after 3 holes. Great sizes though and comes with spare bits and a spring loaded dimpler.

They don’t have the proper sleeve size for the drill bit, there junk.
All the countersink sizes for the relative drill bit size don’t work they are too small. Poorly thought out.

They are not quality at all if you are looking for a cheap crappy uncentered and horribly design tool then look no farther.
