Love my eshopps S-200. Seriously, it is a fantastic skimmer; quiet, powerful, well-made, lots of features, easy to service, dependable. I bought a second one for a different tank. I can't speak to customer service, as I've had no reason to contact them. And I probably wouldn't for most issues, anyway. If the pump on one of my skimmers went bad, I'd replace it with the spare Sicce in my gear cabinet.
