OhO 32GB HD Camera Glasses - 1080P Full HD Recording Smart Glasses with Built-in Camera & Blue Light Blocking Transition Lenses | Perfect for Travel Vlogging, Hands-Free Recording & Outdoor Adventures

I purchased these sunglasses to wear while riding my motorcycle. I figured the camera could capture some cool scenery while I was riding. With my half helmet, the glasses fit very well but wearing with a full face helmet is a different story. I wear an XL HJC helmet and the thick frames of the glasses make for a tight fit as the helmet padding compresses against the frames, squeezing my temples. After about a half hour, the pain was unbearable and I had to remove them. Your fit may vary based on head size and helmet design.I was very pleased with the video quality and sound and I was able to create a montage video from various clips.I thought the frames were matte black based on the Amazon photos but was pleasantly surprised that they arrived in gloss black.The glasses come with a 30GB SD card installed.Battery life: I left it in video mode until the battery died. The battery lasted 1.5 hours. During this time, I was able to capture x 9 10 minute videos. Each video was just under 1GB in size. The SD card is 30GB so you'll capture approximately 29 10 minute videos. That’s almost 5 (4.8) hours of video. By editing the settings file, you can lower resolution and increase your video captures. I’m assuming if you continue videoing, the older videos will be overwritten by newer ones which is common practice.Video: The video is pretty decent as it claims to be 1080 (not 4K). With the photo capture, you have to remain very still to capture a decent photo otherwise it will come out blurry.The video is captured in 10 minute clips in .mov format.Style: I like the style as they remind of my Oakley Gascans with the wide wrap arms over your temples. They can even be construed as goggles which wouldn’t be too far off. I’m OK with that reference as goggles are associated with motorcycle riding.Design: the right arm contains the 2 function buttons, charging port, SD card slot, battery and controller chip. For this reason the arm is almost ½ inch (4.4 in.) thick. The other arm has to match thickness of course. The power/video and camera buttons are prominent and easy to control. (Although not accessible when wearing a full face helmet).Hint: Follow these instructions to get the proper time stamp settings on the video.Create a .txt file and name it SetTime. Add the following line of text with your current date/time: 2022-05-21 10:32:00. Save to the Settings folder of the SD card.Overall I can only give 3 stars as my biggest gripe is the bulky design. Battery life is approx. 1.5 hours which is not bad. Improving these 2 points would increase the refinement and value of these glasses. A plus that they included a 30GB SD card.For the price, these glasses are a bargain as long as they hold up.
