Here’s a few of the many positive feedback’s we’ve received..

Thanks so much for this very well thought out product!  We have several remote sites that are off grid which we needed to monitor, after searching around and trying several solutions we finally found your product. we use it to monitor battery levels and charge current, and to switch loads on and off.  The software allowed us to easily setup conditions to turn off cameras when battery levels were low and to start the generator.

We’ve installed at least 20 Q4’s at our wireless towers and couldn’t be happier, they’ve always been easy to use and extremely reliable.  Several of our sites are over 6500′ and inaccessible for weeks at a time during the winter and the Flexs Q4 has always performed flawlessly.  Previous to this we would have to replace our monitoring devices after about every lightning strike.
