It grows on you
I've had the ext batt and cover (Hyperion) for few months and I loved the batt right off the bat but the cover took me a bit.
Ted A makes some excellent points nice write up
Here are a few more
+ I've got big hands (I can palm a medicine ball lol) and the extended bump along with the grabby case make handling the phone much easier. Stock its like trying to hold a wet watermelon seed.
When setting on a smooth surface and using the screen (playing a game mostly) it doesnt fly across the table and onto the floor, the smoother the surface the grippier it is.
I left the phone on my lap and jumped out of my truck.
It did a half gainer onto the asphalt with absolutely no damage. Thank you Hyperion.
- It doesnt fit in any car or desk cradles that I've tried
Guess thats par for the course.
As Ted said the physical buttons are covered and the small indents are undetectable at least by my sausage fingers. It also negates the back lighting on the buttons.
The grip turns it into a tug of war sometimes when it comes time to get it out of your pocket, especially when sitting down. The neighbors might think your playing a violent game of pocket pool and tell the kids "get inside now"
All in all I wouldnt give up either, I forgot the cover at home one day and realized how good of a job it does. I handled the phone very carefully the extra weight and my track record for smashing small expensive and delicate things made me uneasy. Once you get used to it you wont want to go without.
