I've used these moderately for about a year - average 1 ride/week. They feel great on the bike, pockets are the right kind & location, and they come out of the wash looking new. I've always worn them over bib shorts - didn't find the included liner too comfortable.
Biggest drawback is the elastic waist tabs. I'm a 32 waist and bought the medium size - I've needed to tighten these a fair amount from the beginning. The tabs secure with velcro on each side, and the velcro has degraded pretty quickly. Recently in order to keep the velcro tabs from popping loose I've used staples and duct tape. I'll likely sew some buttonholes and buttons next.
