I've been testing the new ones from Uvex since mid-December (2014) and I'm absolutely delighted. Anyone who knows me as a tester knows that I always have something to complain about and very rarely give top marks. And the Snowstrike VT promises a lot, but also delivers a lot.
First impression
The first impression is no different to any other pair of goggles. Only at second glance do you notice the small electronics on the right-hand side of the glasses. Super small, inconspicuous and insignificant in terms of weight. You don't have to be a tech freak to operate the glasses. A small button at the bottom of the electronics allows you to make all the settings. Double-click to change the color (clear, blue, red and purple). Simply click to switch the goggles from light to dark or press for a few seconds and the automatic system is activated, which then switches between light and dark in just 0.1 seconds depending on the light conditions.
Practical test
I tested the goggles in all imaginable conditions in Japan: from the heaviest snowfall to icy cold or super wet sticky snowfall, through to warm, spring-like and very bright sunshine. Officially, the glasses are rated S1 to S3 (on a scale of S0 to S4, with S0 being clear lenses and S4 being lenses for very strong sunshine), which I can understand. I am VERY sensitive to light and would like a stronger tint in sunny weather.
The battery is supposed to last 30 hours and is then charged via USB for five hours. So far I have not been able to find out if there is a low battery warning. An occasional flickering of the tint would certainly be helpful if, for example, there are still five hours left.
Now to the other key data (original text from Uvex supplemented by my impression).
