I've had no dealings with their customer service, but their advertising is full of fabricated images. Looking through their site I didn't find any of the "through the tube" pics that were actually looking through their product. Most were day photos stolen from photographers websites then photoshopped green. Any actual night vision pics were stolen from military or hobbyist websites and weren't using ATN equipment.
The only legit "through the tube" images I've seen of their products are stuff that end users upload.
Personally, I wouldn't expect much in the way of customer service from a company that markets their products so obviously deceptively.....
