From the users point of view there are two things that could have been done better:
1) the volume buttons don´t stick out so they´re a bit hard to find by touch ...on the other hand you don´t need to find them anaway - pressing any nearby area close to the volume buttons is enough for initiating the phone´s volume buttons (but sometimes it can be annoying when you just want to pick up your phone and the unwanted double press of the rim can initiate the phone´s "volume down" button and thus start the camera)
2) it´s a bit slippery with its´ plastic silver rim - but fortunately the rim is detachable. After removing it you´re left with some little edges on your rubber case which are indeed great for picking up the phone.
I also think the phone (titan colour) looks better in this cover without the silver rim - just matte black rubber case...probably a silver G5 would look better in this case with the silver rim on ... But as I said if you remove the silver rim tha matte rubber cover fits any colour, looks a little smaller and the grip is great.
Anyway your phone is perfectly protected with this case - the soft high quality rubber will damp any possible drop.
