I'm between...
I don't like Powersafe Rx's-but purely because for me there is not a suitable battery voltage available. As JR I want to run my servos just below 6v...as designed!
I use Powerbox products exclusively and trust them 100% (as much as any electronics-which I don't fully understand,so don't trust!)
I've never had an issue with any of my 30+ models currently using PB products...and that's as good as it gets as far as I'm concerned
