99.9% of customers don't care what you use to clean windows just so long as you clean them.
I have a diy system which works the same as any bespoke all flashy state of the art and over priced systems that ALL the wfp suppliers supply, not just Ionics.
as for this forum going downhill, well we all can post what we like within reason and now they have made a few changes by offering advertising spaces to any cleaning suppliers, that is good business sense to them, and as for the suppier who is paying over £200 per month to advertise, if it is generating the business to cover this cost then the will be happy as well.
Until that is some customer comes on here and slates, either their products or after care service, then the price might be a bit to high.
As for the debate with wfp and ladders, this will go on for ever or until the next new piece of equipment comes out that makes wfp obselete.
