Unfortunately already over

Did the end of March 2014 will receive slippers.
Now after almost 3 months (mid-June 2014), I regret to say that they dissolve at several points to.
This black sole bottom I made after 5 weeks the first time, because the seam had come loose.
"Can happen times" - I thought. But now it is so that on both flops disengages the front sole and the opening at the big toe is torn. For 18, I expect actually that slippers should last longer. I would no longer buy nor a friend. 2 stars, there is only the reliable delivery, amusing design and that they have kept warm properly.
