First for the positive:  These are well-constructed, compression leggings - not the thin, baggy stuff that seems to be flooding the market.  Now for why I gave 4 stars and not 5: Normally I'm a size medium in all other brands of leggings (Danskin, Athletica, etc.), but not these.  To give you a more accurate picture for comparison, I'm 5'9", my waist is 27", and my hips are 37".  I had to return the Size Medium as they were way too snug and the ankles landed about 5" above mine.  I instead got the Size Large which fit better, but the ankles still sit high - about 3-1/2" above MY ankles.  Not a biggie.  Otherwise I think they're worth the extra $, but we'll see how they hold up after a few washings.
