The 4 x 6 rug pad was good quality and actually had the advertised rubber non-skid backing.

The 3 x 5 rug pad ( same company) was garbage.  It was supposed to have a 
rubber non-skid backing.  Instead it had a spray adhesive backing.  The felt pad
was folded over the adhesive backing..................when I un-folded the pad the 
backing pulled off in many places..................certainly not the "premium rug pad"
that was advertised.  I expect better. I have requested a replacement.  Also I posted
a negative review about this 3 x 5 garbage rug pad I received.  

I have been very pleased with previous orders, but I am certainly disappointed with this
order.
