Review on Propet MPED25 Smooth Walking Pedwalker by Mark Repp

I am diabetic, weigh 300 pounds. The bottom doesn't wear out after 4 months, but my big toe sticks out when I walk, so the seam at the top rips. The main reason for their rubbish is that the strap goes beyond the velcro and can't be tightened and had to wear a sloppy loose fit for a month. 2 tapes would be better.
