I bought a set last week the
Black Recon Jet with changeable lenses
Directions out the box are a bit "sketch"!!! They are supposed to be "like a memory stick" well I plugged them and nothing. Change cable, still nothing WTF!!

Email to Tech Support nothing back within an hour so I decide to call the number on the website. Nice girl answers and I ask for Tech Support. No Tech Support at that site. She asks what is wrong and I describe the problem. She casually says "You need to turn them on first"!! What "memory stick" do you need to turn on first

I felt like an idiot
Anyway played around with them, updated the firmware. It downloads as a .rar file so you have to get something to decompress it. Not sure why they cant just use a .zip file like 99.9% of the computing universe
The settings are easy to change from the PC program interface but the myriad of button pushes to try and change them on the glasses themselves defeats the simple purpose of POV(In my humble opionon)
They are heavier and less comfortable to wear than normal sun glasses but not to bad. I am currently not able to ride so I have not tried a helmet test with them.
THE BAD
You have no way of knowing if they are turned on or recording without taking them off as the LED's are all out of sight. They really NEED some kind of audio warning or the LED's visible to make it easier to know if you are actually recording or not. I missed a whole 30 minutes that I wanted to record because I thought they were recording but were only switched on.
Still cant figure out how to change the lenses and again no instructions, I really dont want to force them or break them. Will wait for some feedback from tech support
Quality of the video is pretty good. I put this together totally filmed with the glasses. Best part is most people have no idea you are filming [youtube]SH3H1DOV7p8 [/youtube]
