Good, maybe a little short
These appear to be metric drill bits, and are just similar to the English sizes. Even the 1 mm size held up to drilling into redwood, with being careful with the drill. The bits weren't as long as the ones I was replacing, but for the price I say 5 stars.

The first drill bit just snapped. Others would not drill in to steel plate. Do not buy.
Totally worthless.

They are pretty standard drill bits, nothing fancy
Decent for the price. They drilled holes. Not the best, but look at that price The smallest one, which was the one I really needed, does not fit in the chuck on my Milwaukee cordless drill. It's too small. Not really anything you can do about it, but I'm leaving this for other people.

Good price, seem to be decent quality?
Just started using them, but they seem to be a good value for the money. Sized correctly, priced well, but I cannot really offer much thought on durability as I'm going to use them on plastic for hobby work.

Superb set of micro drill bits
I needed 1mm size, and this set provided excellent product. Drilled with Dremel and penetrating oil at faster than recommended RPM, but bit performed wonderfully through hardened steel. I could not be happier.
