Customer Reviews
I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

—— Codreanu from Romania

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

—— Kekarios from Greek

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.

—— Singh from India

First of all I'd like to thank you for you're prompt service. The system now works perfectly. I left a positive response on your web site. I hope it attracts more customers for you.
