Destructively Limp
Drill is sharp and drills well, but if it is spinning in open air (say, when sticking out beyond the item drilled) it starts spinning in a cone, apparently because it is not as stiff as other bits. Seems like all the flexing involved will eventually break the bit in two, and it is also scary.

Seems durable and reasonably sharp
I got the 8" long 1/8" bit for pre-drilling holes in cedar fence boards so I could easily screw the fence boards onto my stringers. Most 1/8" bits are short and can only drill through two 5/8" cedar boards at a time but this 8" bit is able to drill holes through 8-10 boards at a time. I had no problem drilling holes through 160 boards. I found the bit held up and was durable. It seems pretty sharp and was able to get through several knots without too much extra effort. Since it's a 1/8" bit and 8" long, I found that I needed to be careful starting the bit so that it didn't bend a little and change the overall direction as it passed through the wood. I found that if I started it with very little pressure and allowed it to get started by at least a half inch, it would remain pretty straight going through the rest of the boards. This bit saved me time for sure. I couldn't find anything like it in any big box stores near me. I liked that the flute length is long and covers most of the body of the shank. I think that feature really helped with the ease and speed of the drilling process. The bit came in a small square double ended plastic case which I thought was handy to keep it from getting lost. I'd recommend this bit.

Exactly what I was looking for
Needed something to drill pilot holes. This should work pretty well. Got two just in case I snap one.

Sharp and stays sharp
Drilled 42 holes through 4x4 posts. The last hole was just as easy and smooth as the first.

broke on first use
I used this in my lathe to drill a hole in a stainless bolt. I went slow, drilled with light pressure, cleared the chips regularly and kept the bit oiled. Got 2 inches in and snapped it off. The tip did not appear dull. Perhaps this bit is for wood and plastic, not steel.

Much stronger than it looks!
I needed this drill to make a hole through a 6 inch long piece of half inch round bar. The drill performed perfectly. Very impressed! I would definitely buy another!

low quality
While it is a drill bit, and will make a hole, it was curved enough that the resulting 8" deep hole was way oversize.
