My mate bought one, but they were more interested in getting it fitted quickly at their convenience, the fitted it in the rear of the van rather than up at th bulkhead, and the training he received was more about ionics systems than the system he bought, and he only received about 30 mins on the glass training.
The system does look alright though, the frame does look quality, but it's was waste of a van having it fitted by the rear doors, I would sooner with pure freedom, much better service.
