Looking at it I would have to say no. The hard rubberized case is... well... rubberized. And it's stiffer. The photo in your ebay listing shows that case to be very flexible. I don't know what that does for protection though.

I will say that the hard rubberized case isn't as bad as it might seem. It's problem is bad QC. I bought five and some were perfect others not. If you have a warped case it will have a loose fit that can scratch. I rectified this with heat and reforming the case and some sanding. Fits great now.

I have a clear protector too which gives me peace of mind. I think the zagg has the same cut. Bear in mind that it does affect the fit. It is more snug or the tabs may not reach but at least I know the case won't be scratching the phone.
