Bests & Worsts Reviews from Amazon

I was really ecstatic to get a pair of these, the reviews were/are stellar. Then after maybe 12 hours of moderate use in the snow and ice they fell apart. I ordered a pair of Icetrekkers to replace them. When the postal carrier came this morning she was wearing Yaktrax. I asked her about her experience and it was similar to mine. Apparently they received a large box of these thing so they could walk their postal routes. She's gone through several pairs in three weeks and other postal carriers at her station are having the same issues with them. Granted that's on the high end of usage for these things. How did they get these positive reviews? Not sure, maybe a bad production run? Fake reviews? Not sure, but whatever they are sending does not hold up well.
