I've had the BC700 (or possibly one of the identical builds under a different brand name) for years, but switched to the BQ-CC55.

The latter is "put in and forget". The former means fiddling with really bad buttons (because you can! Not really because you have to. But if I can manually set and micro-optimize the charging current, by God I will).

I worry much less about charging nowadays.

I can't say I've used the custom charging current options, but the refresh mode has rescued some batteries that (very unscientifically) did not seem to be holding much charge.

IIRC the default behavior is to charge at 200 mA and discharge at 100 mA.
