Yep.I bought a pair of Pearl Izumi's ($55) in summer of 2005, wore them for six months, and the gel pads peeled loose and fell off. Wore holes in the places were there were no pads, too. I also have a pair of Bell gloves I got at WalMart for $15; got them in 2004 and I'm still using them today (although they're finally beginning to wear out). They were very comfy right from day one. No more Pearl Izumi's for me.
My LBS just got some Bell's in....the classic old school style with real leather palms and crochet back. They'll be my next pair.
PS- another brand I can recommend is Netti. Very comfortable and so far, way more durable than Pearl's.
