Flexible and easy to manage your schedule. It is convenient to control the phone.
I bought two controllers S1 for RV8 and one T1 controller for CP40.
I love this product.
My friends also bought a very satisfied.
I recommend.

Product is really valuable for the new technology in this hibbby

Muy buen producto. estoy usando dos, con bombas RW-8 Y va muy bien. Te permite ajustar los flujos de agua, según tus necesidades. Totalmente recomendable...

Decent product, very convenient, you can set an hourly schedule pump, like me. I bought a second such product. I recommend to everyone.

It is a lightning!!! Very much the design was pleasant. Functionality is good, but demands completion, the same beginning just, all ahead. It would be desirable that one controller operated eight pomps.

Я купил бы себе этот прибор, если бы было управление под windows 10 mobile

Works as designed, simple and easy to program!!!

It is a simple and easy way to control my RW-20/PP-20 Wave Maker. The only thing I would change, is to be able to manage the speed % on every setting. Anyway, Im fully satisfied... LOVE THE PRICE & QUALITY!

This thing works great! Great price on a way for you to get wifi access to pumps and set custom programming. connects easily to phone, but you have to keep switching wifi connections to do it. App needs some improving, like being able to name the pumps instead of Pump A, Pump B.... It also needs to be able to handle more than just 4 pumps. I have more pumps than I can control. Nice manual "feed" button on outside front of case to allow feed mode without getting out phone. Overall excellent product for price.
