I've owned a few pairs of these now, here are some thoughts.

 They look good, and look just like a regular dress sock to the average person.
 Lightweight and provides good compression.
 They are a bit thin, especially on the heel and could tear if you don't put them on properly. (I find that rolling them down to the ankle, then slipping them over your foot and rolling them back up is the best way to put them on.)

Overall, I've tried a few different styles, and for the price, look and feel it's the best compression dress sock I've used. I can certainly see how some have tore, but none of mine have. Use the high-res chart I uploaded, that will really help in choosing the right size.
