Hi, I have three Aqua-dapter's and think they are fab.

I couldn't agree more. Heading for our fourth shortly.
As the previous post on this has been locked - it does annoy me when a 'Custer's last stand' posts in a last ditch effort to get noticed and runs down a product and after sales service of a company that doesn't deserve it.
This doesn't do a service to other window cleaners as stated. It's in the same class as someone coming on here telling us that Gardiner's has cr*p products and after sales service.
For me, I struggle toward the end of the day with an aching back - so bending down to pick a tap up to switch the water off became a real problem.
I had looked at Peter's Autobrush but wasn't convinced that their on/off application was the ideal answer. When the Aqua-dapter came out, we saw this was the ideal product.
The MK1 did have durability issues, but the MK2 has proved superb for us.
Full marks from us.
