You've never had a problem with the clips? Mine was broken on arrival. That was reported to customer service when I wrote them about the battery life problem (two weeks before the firmware upgrade). Fortunately, I already had a CaseLogic for the PRS 300 (long story), so it doesn't bother me too much.
Customer service never responded at all about the broken cover and never sent a follow up email that the new flash fixed the battery problem. The last official word I received on that issue was that I should turn it all the way off if I wanted to preserve the battery. I guess it's a good thing I read the forums.
