Just by seeing that pic my first impression is that the phone is a little too exposed. i'd go for more protection that what that has to offer... just my opinion
I have used one for years. Used it for a Pearl, Curve, and now have a Storm with Innocase II and this holder. If I was to have one complaint, it would be my shirt gets caught in it sometimes when reholstering....not too big a deal.
I have never had this the phone get damaged or come out of this holster unintentionally.
