Try their wax before you talk shit. They are actually really awesome people that support the local snowboard scene to a great extent.
Union makes mediocre bindings. They're not terrible but other companies have advanced beyond what union currently puts out, big name riders or not.
I'm pretty comfortable talking shit about them as a company, from the way they market/spam this site. They could make the greatest wax in the world from bits and pieeces of ground up unicorns and narwhals and I still wouldn't buy it. My decision about them is based solely on the decision to constantly spam the board and dredge 3 year old threads to hock their wares. One thread would be fine, responding to a wax threads would be fine, but they start like 5+ threads a week rather than just updating their original thread. This type of "marketing" is just obnoxious.
