Let me start by saying this little box of magic had me at 'scalding hot shower'. When I first installed it, I cranked it to max settings and nearly turned my bathroom into a sauna. Lesson learned - this thing gets HOT. After adjusting the mix with some cold water, I found my perfect shower temp.

The digital display feels futuristic, though navigating the menus is like solving a Rubik's cube. Why does it have 3 power levels AND 10 settings? I still don't fully understand, but I've settled on a sweet spot that works for my Florida climate.

Where this heater really shines is in our RV. The compact size is perfect, and it delivers consistent hot water for quick camping showers. Just don't expect to run multiple faucets simultaneously - it's strictly one-at-a-time operation.

Installation was straightforward (if you're handy), but heed the warnings about proper electrical requirements. My plumber friend helped tweak the water flow, which made all the difference between lukewarm disappointment and perfect performance.

Two years in, it's still going strong through daily showers. For the price, it's outperformed my expectations - though I wouldn't recommend it for extremely cold climates unless you enjoy brisk showers!
