Small size; I can attach it to any of my remote control toys by simply sticking the velcro strip together with a 250mAh 3.7V battery (sold separately). The battery lasts about 20 minutes on medium settings. Channel, band and power adjustment is done by long pressing for 2s (band) or 5s (power). Speaking of power; Make sure you have a HAM license (technically enough) to broadcast over the air. The default setting was max power so be aware, don't connect the battery unless you have a license. So far the flight range has been great, but I haven't done ego flights yet. Image quality is good. I am using a Skydroid 5.8Ghz dual antenna receiver with 2 cloverleaf antennas connected to a Moto G phone (also works on my Linux PC as is and on a Samsung tablet). Longevity: My 4 and 8 year olds are unknown. Carefully steer their caterpillar tracks and the camera has survived many falls and still works. ).
