## Customer Reviews

### ⭐⭐⭐⭐⭐ Defective and disappointing
*by L***U on July 14, 2025*

WHAT A WASTE OF MONEY 🤦I gave it five stars because I needed to warn people products that don't work or work but don't last, we bought this after I read every positive and negative review I figured I'd give it a chance and it worked perfectly until a month ago the date today is July 14th 2025 to give you a perspective, at the present moment it won't stop flashing and it doesn't stay warm, it's on and I can hold it in my hand underneath the water, so now back to searching for a submersible heater for my turtle tank, buy at your own risk.

### ⭐⭐⭐⭐⭐ Long lasting, easy to use, best value for your money,
*by D***G on September 3, 2024*

I bought this a year ago for 2 of my oscars in a 55 they’re fully grown now and I’m building a indoor pond for them, I bought this heater a year ago and I still have it and it still works perfectly fine and keeps the water at the temperature you want it to be, warms up from 60° to 84° in about 40 minutes, I just bought another not because the one I bought broke but because the pond I’m building will need 2 this is a good product long lasting best value for your money sleek light weight easy to use

### ⭐ pre 2023-great. since 2024, any that look exactly like this & avail from a number of brands are junk
*by P***. on September 4, 2025*

stopped working in less than 8 months of use... The market seems saturated with these since 2023 and prior they lasted 3-4 years and have some still working purchased in 2020... I seem to be buying and replacing any bought in 2024 again and again while the ones purchased in 2023 and earlier are still around and kicking... Frustratingly ridiculous
