Ya, I always had great luck with my Proclip until I caught it on the end of it on a book shelf and snaped the clip part in half'

Which Seidio clip are you talking about?

I only have experiance with the Seidio clip type and cradle type for the T650 also the Proclip for the T600 and T650 and I can say with out a doubt the Seidios have stronger clips and hold the phones more securely
