RX 100 Grip, Richards Vs Flipbac

Personally that looks like a small piece of tape, and I find it an ugly addition to this camera. If you don't want to attach a separate grip, I'd look at tis one:

That looks beautiful and enhances a bit of grip.

I received Richard Franiec's grip for my RX100 a few days ago and it's a perfect fit, just like the ones for the S90 and S95 were.
