Although the image quality is acceptable, the wind makes too much noise. I don't like the button on the left and outside. I prefer the button on the top right side of the frame where I can use my right hand and thumb under the frame to keep the goggles from moving when I toggle them on and off. There is no haptic or acoustic feedback when turning the glasses. The camera is on or off, so you lose track of whether you're recording or not, and you have to take off your glasses to look at the LED. Even though I adjusted the date/time using the SportDV.txt file, the glasses still show the wrong date/time. For some reason the instructions don't mention how to change the config, so I have to assume it's just a matter of changing the config file and saving it. However, this does not work. All in all, these glasses have more issues than I expected, especially at this price point.
