Good Top Off Bad Instructions By Mike on 3/25/13

The instructions on this top off could be WAY easier to understand if it didn't have 6 different languages on each page. Also, it should also state in there that you need to soak the opitcal sensor in soapy water and gently wipe off the polishing residue on the sensor before installation, also there is a dial on the inside of the controller that you need to set depending on the size of the aquarium or sump that you place the sensor in, the dial basically sets the dosing the pump pumps water into the tank/sump. A little better instructioni pamphlet would give this product 5 stars!

I have this running on my aquarium and it is spot on and fail proof . the back up plunger has not been activated Probably because the top off system works so efficient, Great product recommend to anyone who is tired of adjusting or just having other systems that fail.

One of the smartest purchases I've made. Expensive but made with quality and plenty of mounting options. Highly recommend!
Worth the Investment By JOHN on 2/24/13

I was a little apprehensive about spending this kind of money on an ATO. From the moment I opened the box I recognized the quality. Works perfect, provides piece of mind, and everything you need is included. Previously bought JBJ but was disappointed due to lack of redundancy. This should be fail proof with dual sensor/float valve.

Pros: works perfectly, precisely, the German way.
Cons: hard to fight off all the ladies who want to get there hands on my tunze.
best topoff out there By chris on 2/18/13

This topoff is the best there is. I replaced my jbj with this and am so glad I did. The optical sensor with a float is pretty much fail safe and my water level stays the same.

I've never had an ATO system, but this unit is awesome! I had no problems setting it up. Sure, the instructions MIGHT be lacking a little, but I don't feel the complaints below are justified.
The main sensor monitors the water level and activates the pump. The other one can be used as a safety shutoff/alarm OR as an alert that your ATO reservoir is empty.
It's your choice!! I, personally, set it up in the latter form and the product works great.
