Question: Is there any warranty on a new set of glasses?
Document: These glasses are junk, they break so easy. Used mine maybe a hours worth then the video went out and they are unrepairable. Out of warranty and can't even pay to have them repaired.
We purchased this and had difficulty getting it to work. We returned it and got another one as the seller said it wasn't working right. We had trouble with the new one too. It just wouldn't stay on to video. I would not recommend this product to anyone.
These glasses are great I have used them a few times now and they are clear and very easy to use.
The video quality of the glasses is okay.But the glasses do not record right where you are looking. I use them for duck hunting and miss a lot of recorded Birds. Wish I woulda spent the extra money and bought the GoPro.
These glasses/cam work better than I ever would have imagined. Took them to Germany and used them while transgressing Nurburgring race track. Good video and great audio. My neighbor liked mine so much he bought a pair.
First of all, the glasses I got did not match the product on the box exactly. The name was the same, but the details varied a little; the glasses I got had to operating buttons, not just one like the box said. Well, that was no real big deal, but there was no instructions on which button to push in order to operate the camera.
This was not a good experience. The glasses are so tight that there's only 2.5&#34; of gap between where the arms meet in the back! I don't know anyone whose head is that small. Beyond being uncomfortable, nothing works. The charging system gives conflicting info between the AC Adaptor and the frame of the glasses. The charge complete indicator tells you the initial charge is full after only two hours, when the instructions indicate an 8-12 hour charge period for the first THREE charges.
great product,highly reccommend to anyone looking to video and needing hands free.Outdoors picture turn out great. Some small problems,you must get use to the camera is taking picture above eye level. You need to look farther down when taking upclose picture.
This product arrived just in time for my first flight lesson. I wore them through my entire lesson which helped me go back over and retain the lessons taught to me. I thought the battery wouldn't last throughout the whole lesson but it did, from take off to landing. GREAT PRODUCT
The only support provided is e-mail support where you have to wait for a reply, then if you have questions, you have to wait again. I'll most probably send this item back to Amazon for a refund. The idea is great, but the quality is poor and the performance is worse.
Answer: The first pair we received didn't work properly and they did replace them.   The second set worked, kindof.  They are sitting in a drawer now.  Check with seller to make sure about the warranty.
