Works well, very configurable, multiple sensor options

I really like this unit as it allows for multiple sensor options in various configurations. Multiple temp sensors, humidity sensor, weight, PIR, ADC, etc. You do have to work within the various working modes though. I've done some limited range testing with the small antenna it comes with. 2.3miles at -105rssi. 8 snr. I've since ordered a couple more of these units. Can't beat the price!
