My wife and I have this anti-slip points since last August, so now since full 7 months, in our shower use. I must say that the issue was worth it. It is no longer on the idea that one might slip. They are discreet but effective - and they are still as effective as at the beginning. Since I have not reckoned with. I have approximately circular glued the points with a diameter of 60cm. However, I have all the gaps stuck into the interstices of the large circular adhesive dots are on the template, since they have the same anti-slip effect. The envelope containing the adhesive dots on something crumpled, and I had been annoyed and thought me, which is certainly a negative impact on the bond, ie durability, in the shower, but this concern was unfounded. About 3 months ago I had to with a good cleaner to the shower and I thought, now is the glue dots would probably solve - but no, they still hold perfect. I would recommend this product highly.
