I did my first job today using this and must say I'm impressed. Its a bit like cleaning windows whilst laying in a reclining chair. The job I did today wasn't very neck intensive with only 1 window at 40ft and then a smattering of lower ones. But I found it comfortable to wear for even downstairs windows. It will be great for those larger jobs or gutter cleans.
The only down side is you look a bit of a plonker plus if you've got a bit of a belly it's not a good look.
