This is a scope camera for longer ranges and sniping, its not good for me as i end up playing at close quarter sites so wil put money towards a 25mm.
It works fine. Works with external power bank. Fits to a 20mm rail system.
Been used 4 times.
Brand new they are 180-220.
Easy to use and connects to app on your phone.
Do not use poor crappy memory cards. They Need to be class 10 cards if you are shooting in 4k with any
