It seems like they're new, so I doubt you'll find any user reviews anywhere.
Just from looking at their website, I would be very, very surprised if these tires were anything but horrible. Oh sure, I suppose there's a small chance that a two-year-old tire maker (established in 2007) with a "20,000m2 R&D centre in Guangdong province" (which is in the tropics, BTW) might stumble onto the formula for making a decent winter tire, but I highly doubt it.
For a measly $160 savings, I sure wouldn't volunteer to be the first Canadian guinea pig to try these out. There's plenty of other inexpensive, quality winter tires out there if you want save a few bucks. General Altimax Artic, Firestone Winterforce and Goodyear Nordic are a few that come to mind, but I'm sure there are others.
