Hi . . Wanting peoples views on the ns50 only please . . . As i have had three in the last 6 months . . The picture is brilliant, and the range is excellent i can see upto 100yards some nights and the overall idea is good ,but i cant help but think although its cheaper than most night vision systems its over priced for the quality of build you get . . The first one i had , had a dark dot in the screen like pressure had been put on it also the connection from the mains plug to the battery was poor , if i moved the wire it would light up as if fully charged and if i moved it again it would light
