How are peoples thoughts on 3rd party batteries on ebay like Momax, or SIDO, I'm tempted, but I'm a bit worried about putting a cheap battery in my n800.

I assume the cheapness would show its head if it stops holding a charge, and wouldn't make it blow up

Has anybody actually gotten any one of these?
