As described; thin, lovely pattern; not overly "sticky" yet seems quite strong for intended uses (primarily, of which, to keep a small portable bench and/or wheelchair from slipping about on sidewalk and driveway). 
Haven't had time to use in a significant capacity to compare to other backing; that said, I do like indoor/outdoor feature!!!
And, w/o being as thick or sticky ... this seems to be as strong as other "under-rug."
Thank You!
