UPDATE to previous review 12/17/20 I have previously given a brilliant 5 star review on the OHO 4K video sunglasses. I soon discovered that they had completely ceased to exist. holds a charge and doesn't pick up anything. I've tried charging these multiple times but they don't charge at all. The last batch (a week ago) only recorded a video error for a second and then went blank without capturing any image at all. I'm lucky it's still possible to return them for a refund. I'm not a "tech guru". I belong to the generation of cameras that you have to send to the pharmacy to have film developed. I come from a generation of black and white TVs where you literally had to get up to change the channel and use a pair of bunny ears as an antenna on the TV. Needless to say, everything I say about your generation of geniuses in this review is likely to be boring. I bought the glasses because I live in a community of "bad" old idiots (like me), which have created many situations where we seniors are afraid to walk around the seniors complex. I bought a small bodycam that I hung around my neck. (Bell & Howell Tac Camera). I didn't manage to see a video of this thing. I chose the glasses model OHO 4K HD 128GB. (I will update this review with video clips in the future). I had a problem right out of the box. The little manual that comes with these glasses doesn't help at all. I asked technical support ( support@langyinelectronics.com ) for help. They responded quickly and sent me step-by-step instructions on how to set up the init.txt file. They also provided instructions on how to save the video to my computer's desktop. I took the glasses for a test walk yesterday and watched the video when I got home. The video and audio quality was amazing. Same quality as my Arlo Pro security cameras. These glasses are very well made. I keep them in the glasses case that came with them. The only downside I can honestly say is the instruction manual that comes with the glasses is completely useless. This company does not have a website to watch instructional videos. The little visual help I found before emailing support was the video available on YouTube Reviews. I am officially blind (glaucoma) and have lost most of my "peripheral vision". In the original video I shot yesterday, I saw something in the video that I didn't notice during the walk. MARVELOUS! There is a bug that hopefully can somehow be fixed in the manufacture of these glasses. The camera lens is not adjustable and there are other options for video goggles with adjustable camera lenses here at Revain. I would send them back and buy "gogloo WI-FI camera glasses".
