Does anyone frequently use there products? I just got the info pack from them and watched the install video and looks to be a good product but I haven't used it yet in the field. I don't do many showers so I am still developing my technique and I really struggle with the mud beds being that I have only done 3. I really like the idea of the presloped floor they have. Obviously it will only work in pretty standard applications but I just wondered what ya'll thought.
