not worth it.
get an energizer charging station, along with the energizer rechargeables. thats your best bet. the charging stations are a bit of a gimmick, they often use low mah batteries.
they're great but be careful though because i had my remotes on one too long after it charged and one of them just died, and the other one kinda ran away.( i lost it)
I have a Psyclone brand station. it doesn't seem to work very well, and the batteries wont hold a charge very long. At this point its randomly flashing. My wish is that it doesn't explode. try to avoid the brand if you can.
