I use it as a base for various detergent and fabric softener bottles directly on the washing machine. Even when spinning at high speed, these bottles do not slip more.
Unfortunately disturb the visible fold lines of the folded delivery. These do not disappear when laying flat mat. I the mat after 10 min at low temperature in the dryer laid flat on the ground in warm condition overnight. After the mat is completely wrinkle-free.
A star deduction for the necessary reworking of releasing of bending lines, otherwise the non-slip mat would be perfect.
