Good product, but needs to include care and use instructions - Night Optics Adventurer Gen 1+ Night Vision Goggles

Haven't used it much yet, but have enjoyed the couple hours of use thus far. Didn't give it 5 stars because the product came with no instructions, just stuffed into a plastic bag and in the carry case. No paper work of any kind. Looks as if it was plucked off a shelf, shoved in a plastic bag and shipped. User guide, instructions, directions to online instructions... would have been nice.
