I presume Clive, that you mean the NCCA Hands On Experience, which we held in Wolverhampton.
The motivation for the event was to demonstrate the benefits and cleaning capabilities of various non-HWE systems, both generic and branded, and allow delegates to try them for themselves.
For myself, I have to remain neutral and not respond to your question, but I felt that all of the systems performed admirably, especially when you consider that it was a hospitality environment with the subsequent soiling problems that entails.
Safe and happy cleaning
