I bought a few refurbished light fixtures from them from them over the years and they've worked as I've expected them. Maybe mine where the short lived units that people returned! The protective splash guard is the similar of their other fixtures design where it seems to be removable. I mean my Nova Extreme T5HO had a lot of salt creep and it is still working other than screws being rusted.
Anyway, the Sat + I got refurb like new from them was back in July 2014 and (knocks on wood), it's still working.
