Very Adjustable to achieve optimal water levels with a great bag of connectors
The cost of the quick connects and RO certified tubing alone makes this worth it. (I had to pick up one of those push to connect on-off valves for another project at Home Depot for $12.55, and this set came with one thrown in). I had a similar device fail in the open position once, so I paired this with an auto cutoff Ortis WiFi Power Failure Alarm with Water Level Detection to my RO pump (https://a.co/d/9YxxFE7). However, this one seems less likely to fail as the RO water comes out right over the float joint which should keep it from getting salt build up to jam it.

Worked as described
Hooked up to my ro system to my reservoir and it worked great kept me from flooding my basement. Fits well to a 32 gal trash can or anything similar. You can adjust the float level to an extent.

Pretty average as far as these things go.
I hate these things. They are hard to adjust. But as far as these things go it is pretty good. I have not come across anything better.

Works like a champ, no more bucketing water
Installed this in my console humidifier, connected it to an abaondoned ice maker line in the basement and VOILA! The humidifier stays full, the floor stays dry, the collie stays static free and my back stays healthy.

Bomb diggity!
dignity! Using this in a 35 gallon water storage container. My RODI system fills the tank so that I can mix saltwater for my reef tank and this auto water shutoff works like a charm. The float can adjust up or down about 4-5 inches, and the float angle can also be adjusted to further fine tune max water level. I likes! I am very excite!
