Arriving packaged in an adequate case, with room enough for the included accessories, these glasses initially feel plasticky but fairly robust. On closer inspection things aren't quite as perfect as you'd hope - some plastic and rubber inserts don't quite sit properly, and I'm fairly sure it won't be long before one of the 2 cables that connects the arms will break at the flex points - mine are very tightly in there, and don't have any play at all when folded.
The accessories included a working 16GB Class 10 unbranded MicroSD card, and 4 sets of lenses: dark preinstalled and clear, blue, pink and orange in separate dual pouches. The lenses are easy to swap out, and they are one part of the glasses that seems least likely to break - they really are held in solidly and clip firmly into place.
But what really lets this down is its ropey video quality. HD it may be but the lens is awful, and the data rate / compression used to commit video to file (in large and bulky avi format nonetheless) means something like even a GoPro1 blows it out of the water.
There are compression artefacts all over greys, which go bizarrely purple, and video is often blocky as the video is mercilessly compressed. If feels like we're fixed in Low quality mode, and like we need a setting to turn HQ on. But there isn't one. The only thing you can do is set time and date stamps, and choose the resolution, which you do by writing text files to the root directory of the card.
It's a shame the video is so ropey because the glasses are light, comfortable to wear and don't look too idiotic, especially if worn with a cycle helmet. I also didn't like the light constantly doing inexplicable things in your peripheral vision, which was annoying as hell every time I was anywhere dark, but not bright enough to usefully see anytime I was outside in daylight ! Also, whoever designed the logic behind the button presses required to operate the camera needs to have a word with himself. It might be logic how that works, but even with the manual to 'help', it's not human logic as far as I can tell. You work it out eventually through trial and (rather too much) error.
Photos are, as claimed 12 MP, but as you'd expect, rubbish lens = rubbish stills, no matter how big they are.
We must remember the price. It's a decent pair of cam goggles if you remember that you're not paying £300 for some really decent ones, or £1500 for Google glass. Just such a shame that they spent what little money they must cost to make on everything except the most important bit - the lens.
