With good lighting, the photos are better than I thought. The videos are also very good (I can't upload any but it's the same as the photos, and with a good image stabilizer) at night, if there are bright spots it looks very good too. The artificial intelligence works well, I have no complaints about the sound. The only problem I see is that the glasses sometimes start talking to me as if I asked something to the AI. The battery, if you make videos, drains quite quickly; by default, it makes 3-minute videos but you can (from your mobile) set them to be a maximum of 12 minutes. The app connects well and quickly.
