Query: About killed me!

This bath mat is incredibly unsafe!! Initially I was thrilled to find it, but within a day it was slipping in the tub, nearly "leveling" me! I tried adjusting it this way and that, to no avail. Finally realized it just doesn't have enough suction cups on one end, so I cut it for safety's sake. It STILL slips around mercilessly!! I'm very sure-footed, as is my roommate, and we have no elders or young kids at home, but I wanted to warn people to be VERY CAREFUL about purchasing this mat. Yes, this material is great for shelving....DRY shelving where feet are not landing on it......but there IS no Grip in this Griptex.
