Okay, so I've been using this bad boy for a couple weeks now and here's the tea ☕

First off - the HEAT. This thing is POWERFUL. My jacuzzi went from 'arctic plunge' to 'tropical paradise' in like 20 minutes flat. Way faster than my old 1300W heater. The temp control is super precise too - I can keep my water at exactly 102°F like some kind of fancy spa technician.

The titanium build feels premium AF. I've used it in both my saltwater pool and regular bathtub with zero corrosion issues. That acid/alkali resistance claim seems legit.

Now about that GFCI situation... mine works fine? Maybe some units have issues but my safety features are all good. The double insulated cables give me peace of mind when I'm soaking nearby.

Bonus: It works in literally anything that holds liquid. My fish tank? Check. Bucket for foot soak? Check. Even tried it in a giant soup pot during a power outage (don't judge me).

Would I buy again? Absolutely - just maybe from a different seller if the GFCI issues others reported are common.
