i was very surprised with this little camera. it powered up as soon as i connected the battery. I used it in conjunction with the ROTG02 Receiver and the Samsung galaxy S10+ download GoFPV from the android apps store. Unfortunately the leads supplied were non responsive so after adding my own micro usb lead and c-type connector i was able to get a good clean responsive picture to my device. Works Great, Arrived in good time,virtually no lag.
Great price and works well.
