Very usable set of points. Awesome price.
I got this kit when the similar few bits that came with my mini-tool did not have the profiles I needed. I wanted to write more information on the back of my kitty's tags, such as alternate phone numbers. This kit gave me the choices I needed.

The end tip of the bit I used was a little out-of-center from the shaft, but I found if I wrote with the bit tipped like a normal pen, instead of straight up & down like a drill bit, it worked pretty good.

Most of the other bits seemed more uniform. This kit does the job I need, and is an awesome price. If you are looking for very high precision items then I think you should first start with this kit, because you are going to pay more than what this costs for each bit otherwise. But if you only want the best, this may not be for you.

YOU GET WHAT YOU PAY FOR.
Would not recomend to a serious carver. The first tiny bit I used on wood snapped just below the carving bit in about 30 seconds. I knew they were not of the best quality but I figured them to at least do better than that.... Even though cheap its a waste of money." I did get a better result from the larger bit. So beware with the tiny ones if you get this...

Good deal for the price
This set of 20 bits costs less than one high-quality diamond bit from other sources, and the bits did the job for which they were purchased.

Used them to drill two 1/8 inch diameter holes in non-tempered window glass. This must be done slowly to avoid overheating and possibly fracturing the glass. Used several different bits to change shapes in the hope of making it go faster. When done, the holes were fine and all of the bits still seemed to have their abrasive surfaces.

I've read elsewhere that a high-quality diamond bit will last for perhaps three holes like these, and that it takes about two minutes to make one hole. Well, it took about 30 minutes per hole, but more than half of that time was spent pausing to let the glass and bit cool off. Since all of the bits still have diamond grit on them, it seems likely that they'll be able to make several more holes before wearing out.

NOTE: Tempered glass probably will shatter if drilled. This window didn't have a "tempered" logo in the corner and looked normal when viewed through polarized sunglasses.
