RAS on the product itself, I bought it for the "stick" on the credence of my kitchen. 48 hours after bonding of the vacuum unit I filled the compartment soap and unfortunately the double face did not hold. Note that I have pasted the entire double-sided present in the package on the sides and center. So I bought the double face with a very strong adhesive power and currently it holds ^^. With respect to the dispenser, soaps "gels" appear to be better distributed as liquid soaps. A small flat on the quantity of soap delivered each request, ca seems a little tight, pity there is no setting. The switch to stop the distribution is a very good thing.
Update: 15 days later than the double face that I purchased separately did not move .....
