Love these shades!  They are easy to install, have a great hidden mechanism for lowering/raising the shades which are also smooth to operate and do away with unsightly cords.  Great color choices, and although the weather has not been cold enough yet to test the effectiveness of the thermal lining, love the option.  Have held up to daily lowering/rasining without damaging the hardware, which has happened on some of our other cordless shades

Pros: cordless, smooth mechanism; good quality
Cons: none so far
