    • Didn't even get remotely warm
It didn't even heat up. I'd return it but its past the return window. A complete waste of money.

    • Buy a different model and name brand
Put in 10 gallons of water for over 3 hours still cold. You can wrap your fist around it under water and barely feel any heat coming off the heater

    • Worked good for our tub
The GRILLME 240V 3000W Immersion Water Heater is a real game-changer if you want hot water quickly for a bathtub or small pool. I used it for a 30-gallon tub, and it heated the water much faster than I expected. The 200-gallon pool option works well too, though it takes longer—still much faster than waiting for the sun. I appreciate that it’s fully submersible and 100% waterproof, so I never worry about safety while it’s in the water. The portable design makes it easy to move around, and the NEMA 6-15P plug means it’s compatible with standard 240V outlets. It feels sturdy and well-built, not like a flimsy gadget, and setup is simple—just plug it in, submerge, and let it do its job. Overall, it’s a reliable, efficient, and practical solution for heating water in tubs or pools, especially when you don’t want to wait forever for the water to warm up. ... show more

    • Actually submersible, heats water. No voltage detected in the water.
Actually submersible, heats water. No voltage detected in the water. I tested it with a foreign voltage detector repeatedly, and no voltage was found in the water. I still wont be in the pool while it is running, but it seems safe. Odd name for the brand, though. The pool that I used it in was way too big for it to keep up with, but it does work. In the attached video, you can see the water heat (wavy color and bubbles) so I guess it gets pretty hot, its just not big enough for what I wanted to do with it. There appears to be no electronics in this device. no timer, no safety shut off. if you plug it into 110v (adaptor included) it takes twice as long to warm up. Just drop it in. its that easy. ... show more

    • You never knew you needed
This is one of those things that you never knew existed, let alone needed. It can be used in a variety of different situations. I’ve used it to heat up water for my portable camping shower, washing the dog outside in the wintertime, etc. It’s easy enough to use that it makes it convenient. It heats quickly and reliably. And the price is comparable to other similar items available. Overall, it’s a great investment for a lot of convenience. ... show more
