I bought TWO cases to compare... Case-Mate & Diztronic.
Case-Mate --> Hard plastic and was difficult to install/remove. Power and volume buttons were very hard to press. I bought black/gray, I did not like the gray part at all. I'm not impressed by this one. Cost was $14 on BF sale + $3.95 shipping.
Diztronic- Softer more rubberized and was much easier to install. Fits snug. Volume and power buttons are extremely easy to use. The feel of the case is great. It covers the entire back and isn't just a bumper like the case-mate. It just feels much better in my hand and looks 1000x better as well. Cost = $9.89 2day shipped from Amazon.
I much prefer the Diztronic and will never install the Case-Mate again. It was so hard to take off I almost cut it off. In the drawer it goes to collect that fine particulates called dust..lol
I found that the Case-Mate is not hard to put on if you do the opposite of what you would do with the Diztronic. In other words, you lead the phone through the front of the Diztronic but with the Case-Mate, I lead the top front of the phone thru the BACK of the bumper case.
Then you push the bottom case corners press against the front of the phone until they wrap around the side and back the of the phone.
Still, I don't like the way the Case-Mate bumper bows out on the side, mainly on the button side. It makes volume buttons too easy to accidentally press. There's already a crack in my Case-Mate from taking it on and off the phone.
I definitely like the Diztronic better.
