Was installed about 6 weeks ago, both salesman and manager came round, after there visit he accused me of wetting the wall with a sponge before he arrived. The damp patch is still there! I was very upset with his attitude. As we can't resolve this problem I certainly would not recommend your product to anyone.£1000 is an awful lot of money for us only being on a pension and we have nothing to show for it! Also the machine in loft has caused the ceiling to come down in the bathroom!!
