This uncoupling membrane seems to be good quality and is much cheaper than DITRA. It installed easily and hopefully I never have to think about it again. I dropped one star because the options are pretty limited in terms of roll length. I used this in combination with heated uncoupling membrane but could not get rolls of the right size so I ended up with a bunch of scrap. (Also, its a little annoying that the thicknesses are different but you can make up for it with thinset.)
