Cindy Mullen Boston, MA

One of the best parts of CUSTOS is how I can add multiple devices on the app and be up on any leak just on time. This way I can get things right immediately. Moreover CUSTOS shuts down main water valve in case of a leak automatically so that’s a plus right there. After I got mine, I ordered another KIT for my parent’s house. Now I can relax knowing that they are safe as well.

I was afraid of the time of the set up but to my surprise it took minutes. From opening the package to downloading the app, everything was where it should be! The directions were clear so I had no problems getting everything where it belongs. Definitely recommended!

I moved to a bigger but older home and wanted to cover every ground ro prevent any disasters. Custos Kit and Water Leak Sensors helped me achieve just that. I put them dark corners and now I go everywhere with a piece of mind. Great for protecting your property whereever you are.

Daniel Ray Boston, Massachusetts

I never knew how importan it was to have CUSTOS until we had a leaking disaster. We spent thousands of dollars to renovation and spent our every waking moment cleaning our home. After we got CUSTOS, we could finally rest assured that it covers the whole house. Even when we’re not there.

I’ve got two beautiful cats at home. And sometimes I have to leave them alone for work. Those times I would worry for a possible leak at home. But with CUSTOS KIT, now I can work with a piece of mind. CUSTOS shuts down water valve and prevent any disaster. My kids and I are extremely grateful for this Kit!
