Query: there's better options

I've had a silicone case on my Treo 650 for a long time. It was thin and the rubber was very grippy (great anti-slip)- once I left my Treo on top of my car (NOT recommended) and drove 10 miles, and the case was so grippy that the phone was still on top when I arrived! After it finally broke I ordered this one to replace it. The rubber on the Boxwave case is much thicker than my original case, so much so that it's difficult to use the 5-way navigator without it doing what I didn't want it to do. The case is not nearly as grippy and slides off my car seat, unlike the original. Boxwave offers full refunds if the product is defecive- since this isn't, I probably won't bother. But in my opinion, there's better products out there.
