Been using this for a little over a year now and it hasn’t shipped a beat. Great ATOBeen in this hobby many years now. So I wouldn’t rate it 5 stars if I felt it would harm someone’s system. Accurate and easy to set up. Fairly quiet operation, but certainly not silent. May bug some people in a quiet room.

I've had probably 5 ATOs in the last 10 years for different tanks. This ATO is by far my favorite. I clean the sensors probably once every couple of months and it hasn't malfunctioned once.

I have it on this 14 g AIO. Multiple very small doses daily. The run dry alarm worked as advertised. As much as my hand in the tank does create an over filled alarm because of my back chambers relatively small dimensions. Pretty impressive so far, for the price especially.Edit. This thing constantly fills to the over-fill sensor. That's bad enough. But it adds insult to injury when it starts alarming because your tank is now over filled.I really wanted this ATO to work. Regrettably they used cheap sensors just like every other ATO.

It's been almost a year and this little topper has been doing well. Every couple of months it glitches out thinking that the reservoir is empty when it is not, to fix just unplug and plug back in. It should fix itself. In terms of reliability I think it is pretty reliable. Not foolproof though. For a cheap and quick system it is worth the price. Has saved me a ton of time and worries regarding my salinity levels in my fiah tank so that is a huge deal to me.

Edit: My friend from the Amazon delivered a replacement pump today. I went straight for the pump and installed it using the first package’s control module. Same failure. Next, I replaced the first package’s control module using the original pump. Failure. I then replaced the entire set-up, jackpot!! It works as it should, I tested both sensors and everything works properly. Very quiet and appears to move a cup of RO water in a few seconds. I’m happy with the purchase, happier with Amazon for the fast turnaround. No more manual refilling for me!!Really wanted this to work on my 90 gallon reef tank with a 30 gallon sump. Watched a few videos and read all the reviews. Spent 30 minutes installing the pump, module, and organizing the wires. At last only one thing to do, turn it on. Nope, the pump won’t pump. I read the troubleshooting page and a few more videos and I believe the pump solenoid was delivered as junk. Hopefully my friend from the Amazon will deliver one that works in a few days. Update to follow….

Wow, the quality of components and the price of unit are unbelievable. What I love; I have a 32 biocube and installed the sensors right in the water level window. The magnets are super strong and when you do a water change you can easily nudge the sensor to the level. Works amazing 👌🏻. Back in the day there were float valves and took much longer to turn on off; with photo sensors it’s faster and more accurate making the environment even more stable.

I had been using a expensive Tunze ATO for the past 4 years. The optical sensor stopped working. This device not only is quieter but can move more water. It's only been 1 month but so far I'm very impressed. You definitely can't beat the price especially when you catch it on an Amazon sale!
