I recently purchased the 1500W Immersion Water Heater with Digital Thermometer, and I am very satisfied with it. It heats water quickly and efficiently. I used it in a bucket, and within minutes the water was hot and ready to use. The digital thermometer is very helpful because it shows the exact temperature, so you don't have to guess. I also like the auto shut-off feature, which makes it safer to use. It is lightweight, portable, and easy to store. This heater is perfect for home use, travel, camping, or even emergencies. Overall, this is a reliable and affordable product. I highly recommend it!

The electrical cord coming out of this thing was so small that it gets hot. After a few hours, the insulation was partially melted, and it blew the GFCI outlet. I had it plugged into. Returned!

I have got this to heat the water outside to give my dogs a bath and to wash some clothes. It heats up so fast it controls temperature really well doesn't get too hot and also turns off when it's done. I love that I can just walk away, have the water heat up and it turns out by itself it's worth the money

I bought this in case of an extended power outage. We have electric water heater and if we lost power for a few days the hot water would run out. So I also purchased a 20 Liter just over 5 gallon foldable vinyl container. I filled it up and checked the water temperature which was 48⁰ F. It's winter here and been quite cold. I dropped the heating element in and it sank to the bottom and laid on its side. I then plugged it into my ecoflow delta 2. After 16 minutes the waterwas at 101⁰F . I shut ac power to the power cord and let the heater stay in the water for about 10 minutes. I also removed it from the container. And added the shower head with pump. That worked well.
