I’ve heard about these cheaper ATO’s overflowing their tank. This one works great and the good news is you will never have this issue if you just turn it on the 1-2 mins/day. It quickly finds the height of the water and kicks on/ into standby accordingly. I have this installed into a 5gal bucket with holes for the check valve and power cord. It lasts me for weeks with a 55g reef tank with lids on. And with a check valve the pump doesn’t get taxed much and should last for a while. The box did arrive wet/ and slightly damaged, but the product was fine. The device’s magnet is strong and holds through about a 1/4” with a very strong grip. The pictures are accurate. Device is about the width of a nickel’s diameter.

I've now purchased 3 times. All 3 of these are absolutely garbage. They work for ruffly 1 to 6 months and then ultimately fail.Reviews say it's great, but notice none of the reviews mention "Years of use".Longevity wise, this gets 1 out of 10. Waste of money.The pump is a 2 out of 10. It's slow, small and breaks easily. It's the kind of pump you'd expect to pay about $1 for.The sensors are NOT water proof and in fact the sensors will take in water and then create a film inside that destroys the sensor.All in all, this is an epic waste of money. Amazon should be ashamed to sell this product, as it's designed to break and you will need to replace it again and again and again.Quite frankly, I'd like my cash back. This is a scam product in which I have 3 of. 3 is enough to prove a point. If the seller or anyone at Amazon would care to interject, maybe we could establish some accountability. For this product, there is none.Buyer beware. This is a disposable product with a shirt lifespan. Absolutely rubbish.

Item works great! And they have amazing customer service! The pump on my first kit burnt-out after few months due to me forgetting to fill up the reservoir before going on a trip and when I contacted the company to see if I could just buy the pump they sent me an entire kit for free even though the issue was my fault.

Update. Customer service reached out and sent a full replacement. All is good again. If I can get another 8 months to a year out of this one I'd say it's a good value for the moneyPump stalls after 8 months and is noisy. Doesn't come back on without smacking it a bit. If the pump was easily replaced then it wouldn't be an issue but it doesn't seem to be the case.

This little gadget has been a lifesaver for me! One less thing to worry about when keeping an aquarium. I would also lists this in my must have pieces of equipment. Very easy to put together (even without instructions) and works like a charm! I use for all my fish tanks! If it ever doesn't work for some reason, shutting off the power and rebooting does the trick every time.

I purchased this product to only use while on vacation. I didn't trust it for everyday use and could manage to top off my reef when working from home. I took one 3 week trip and came back to an awful grinding sound from this device. I'm unsure when this malfunctioned, but it's safe to say it's unreliable and likely just unsuitable for a saltwater tank.

Update: I was sent a replacement which works perfectly. I updated rating to 3 stars because they did send me a replacement, but the first one should have worked.I purchased this to maintain water levels in a freshwater aquarium sump. I followed the instructions exactly and found it to be easy to set up.Unfortunately, the pump (which is submerged in water) will not come on. The sensor light is blinking blue to indicate that the pump is on, but the pump is not running. Of course, this thing is useless without an operational pump.Why they include such a cheap pump is beyond explanation; it could have been a great product. (Picture is of the tiny little pump that is included)

I would like to start of buy saying I have been in the aquarium hobbies for over a decade and had always taken steps to reduce evaporation as much as reasonably possible. However after many years of topping off my tanks manually I decided to look in to an ATO, after reading many reviews and seeing a few videos I settled on this one and I'm glad I did. The ATO is very simple to to set up in just a few minutes. The sensor that goes inside of your aquarium is very small and the magnet used to secure it in place feels adequately strong enough that I'm not worried about it falling inside of my aquarium. I purchased a smallish 7 gallon water container one would use for camping to use as a reservoir for hold additional water and the small pump head fits very nicely inside. So far it has been working great. There is very and I mean very little noise heard from the pump when it kicks into action and the only time I've heard it was when everything in the room is shut off and its stone silent in the room. The only draw back that I can think that may throw some people off is the sensor it's self is a very very bright night light so best not to use in a bedroom I'd say if you like the dark that is but seeing as the aquariums in question are located in my home office / game room it doesn't bother my in the least. I have plugged my ATO into a smart plug to make water changes and gravel vacuuming easier as I can disable it while doing so. Hopefully people find this review helpful. 😊
