My battery is alright, so I don't need one of those yet. It's just some days I have some really high use (torch and BT) and want to have something I can grab that's small.
Then again I guess I can just grab the case and change it. So maybe not a bad idea.
Cheers.
Would you say it's a comfortable fit in a front mens Jean pocket?
Kinda looks like a pack of cigarettes size.
