Got my brochure, and very impressed.
Was speaking to a fellow window cleaner the other week, and we were chatting about a firm who has a couple of Ionics Thermopure systems, and he mentioned he had asked them why he spent the money on them, and the guy told him it was not worth the hassle not. Too busy to DIY, or deal with unproven set ups that would take their vans off the road if there were any problems.
Having never experienced the set ups, I would like to think it's that old cliche of "you get what you pay for".
Certainly look very good in the brochure.
