I was really impressed with the quality and lack of blurring, excellent. I'm a hunter and have yet to test this, but hiking and cycling work great. The lack of a microphone suits me, there is no wind noise when watching a video. I don't need a microphone. It took me a little time to get used to the controls, the on/off is in a good place. It moves very little. You don't need a phone to use the glasses. I paid a whopping β¬45. I looked at others and this was the best buy for me and my app. It took me a while to get used to the 2 LEDs, one big and one small. The instructions weren't very clear at least not for this 79-year-old hunter. These are just the tickets for me. I'll check out archery when I get home from Florida. Excellent glasses.
