hey its been running for two weeks. was 25 bucks, is simple to set and run, if you know the metric system it also has that option. really i dont sweat the heater and recommend it but hey, maybe it will bit me in the rear later on. UL listing is a hotly debated subject because it goes beyond the standard of allowable ratings. Its a secondary zone and requires a lot of money to go through testing and approval, if you google it you will see why some of these companies dont care to get it on there product simply because of costs and effort. To me, who lived in iraq and afghanistan, i have seen crummy wiring and electircal devices. No kidding some true crap shot haji stuff. This is heater is sleek, well sealed and meets my standards. I did a full underwater test, and no stray electrical and yes the digital readout still works fully submerged and so does the adjustment button.
Hope this helps, but remember what you and i consider safe are two completely different things and i can vouce for the item because its running a 130 g system safely.
