Even with my glasses left a more than desolate impression. After a slight bump of the frame broke. Glasses were therefore unusable. Use previously only possible because the camera on the slopes always after 10s with the message "battery power low" ausschaltete. This process then settled but repeated several times. Only at the cottage it went smoothly! All in all not advise because no goodwill was acquired by manufacturer o. Seller and, moreover, any repairs / replacements are supposedly more possible due to the product ages! Prima!
