I own the Marine
SSC-1500 Smart Charger, 2, 10 and 15 amps Plus maintenance mode for Flooded, AGM and GEL Cell.
I use it mostly on the neighbors trucks and my lawn tractor.
And the
SC-300 used mostly to maintain the Boat.
At 3 amps it is more than just a maintainer.
Once the battery is full, it comes on for about one seconds every 3 minutes.
Both have worked fine for years.
Admittedly the Fan in the Big Charger is notorious for becoming noisy after a while.
For $5 on ebay, a replacement Ball bearing, common computer fan, plugs directly in and solved the noise issue.
Keep in mind that reviews are mostly going to be coming from the people that have an issue or just like to complain.
You never hear from the silent majority that like the product.
Schumacher prints their service contact right on the product and it states that if you are having a problem to not return it to the store, but to contact them to get it resolved.
