Works great
I have several of these they work great (unless snails cover the sensor) make sure to get the dual sensor though had a lot of problems with the single sensor 1

Unreliable ATO
Randomly the sensor does not signal the pump to fill. There are no LED warnings on the sensor when this occurs and the sensor is clean. This faulty ATO requires I look at the sump once a day to make sure it is filling properly. The workaround to this unreliable ATO is to power off and back on and magically watch the pump start filling to the sensor level without issue until another power cycle is required. I highly recommend looking for another ATO for your aquarium needs.

Not reliable, doesn’t sense water level dropping
Not reliable. Randomly will decide to stop working. I’ll notice my reservoir hasn’t moved in a couple of days to find this ató system isn’t working. Other times when my reservoir runs dry there’s no alarm to alert me. I’ve tried replacing the pump but the sensor doesn’t seem to work anymore even though the blue light is on. I’ve been using it for almost two months and need to find another ATO system

Very short lifespan
It worked well for only about 2 months and then completely stopped working Update: bought another one thinking I got a lemon last time. This one stopped working in few days. Thankfully it is still within return window. I am done with this product. This product seems to be a scam.

Perfect
Works perfectly!! Quite easy to install except inserting the tube to the pump - just inserted back of the tooth brush to it for few secs, so once it expanded a bit I could fix it to the pump easily. Tested only 2 days, so far so good. However, the box shows 2 sensors which is quite confusing as I thought it’s the upgraded model with dual relay so I assumed I’m getting 2 level sensors.

Comes with foreign power plug
The product works well but comes with a foreign power plug meaning I had to go out and buy an adaptor to use it in Australia. This fact should really be noted somewhere noticeable on the listing and adds to the expense of the item.
