Okay, let me start by saying this little gadget is a game-changer... when it works. I bought it mainly for my inflatable hot tub because who has time to wait forever for warm water? The first time I used it, I was SHOOK – it boosted the temp by 3°F in like 45 minutes. Magic!

BUT (and there's always a but)... my first unit literally died on the third use. Thankfully Amazon replaced it super fast, no questions asked. Fingers crossed this one lasts longer because when it works, IT WORKS.

The stainless steel build feels solid, and I love that it comes with a digital thermometer (though mine sometimes gets wonky). Pro tip: don't trust the thermometer blindly – keep a backup meat thermometer handy like I learned the hard way.

For small jobs like heating a 5-gallon bucket? Perfection. For trying to heat an entire bathtub? Girl, don't even bother – you'll be boiling pots on the stove like it's 1823. The extension cord gets HOT too, which sketches me out.

Random bonus: It's cute with those little hearts on it? Like why is my water heater serving looks? Anyway, solid 3.5/5 stars – amazing when it works, frustrating when it doesn't. Maybe buy from somewhere with easy returns just in case.
