## Customer Reviews

### ⭐⭐⭐⭐⭐ Broke after a day, got sent a new one!
*by E***N on April 20, 2024*

I mean, I like the overall design and stuff, worked great for a lil bit, but by next morning it was stuck flashing in reboot mode, only when it was trying to refill too. The pump would turn on for a fraction of a second before turning off, tried unplugging it, moving sensor locations. . Nothing-update-The seller reached out to help resolve the issues, I did end up returning the previous pump and got a new one for free, and this one has been working without an issue! Sensor seems accurate and it comes with a generous amount of tubing, do be warned the LED is a bit bright though, definitely better for the sump.

### ⭐⭐⭐⭐⭐ Effortless Aquatic Bliss: Simplify Your Water Management Today!
*by M***X on November 6, 2023*

Never have I come across a more reliable and efficient solution for managing water levels than this. The setup process was a breeze, thanks to the clear and straightforward instructions that left no room for confusion. Once installed, the system proved its worth with flawless precision, ensuring that my tank remained consistently full without any hiccups. What's truly impressive is the remarkable strength of the accompanying sensor's magnet, which firmly secures it in place, leaving no room for worries about displacement. This innovation has made my water management a hassle-free experience, allowing me to simply set it and forget it. Kudos to the creators for providing such a simple yet complete solution that has transformed my aquarium maintenance into a stress-free delight.

### ⭐ Not worth it! - edit: don't waste your money!
*by D***Y on January 8, 2025*

The first pump gave up in a week, so got a replacement, but the new one is barely pumping to keep the water levels. I have to manually top it off everyday. I have a 50 gallon tank, and also live in low humidity state, I think the pump can't keep up with all the refilling it has to do.The pump is very silent (when it works, lol), and the setup is easy to install. Would recommend for a smaller tanks (~30 gallons).Edit: the replacement stopped working too! Don't waste your money.
