Knockoff Maxtrax on ebay

[NZ4runner]

Has anyone used these? Im thinking of getting a set just because they are so much cheaper than maxtrax... Im a little worried about quality though. Like ive seen how maxtrax bend and flex when driven over... Im wondering if this type has lower quality material or what. Whos got some info?!
