Promariner vs Sterling battery charges

[Monty]

Looking for owners with experiences with the Sterling line of battery chargers. They were co-developed with Promariner and match the Pronautica models but less expensive. Anyone have reasons not to use the Sterling charger? I can find nothing negative after lots of searching. Thanks.

I replaced my old Charles charger with a Sterling ProCharge Ultra almost 2 yrs ago and have been very happy with it. Easy installation, very customizable and seems to get excellent reviews.
