Hi Tony,
I have the Airflex Turbo with the triple vac and 600 psi pump, (have you bought yours yet Simon!) and I have to say that I'm very pleased with it. It's well thought out, simple to use, access to all the workings is quick and easy, and the silencer really does work! Performance and results have been excellent so far, (only had it 3 weeks) and I can't fault it.
Usually I would not take a chance on such a new to the market product, but imho this has been well designed and developed from scratch, rather than putting something together using existing mouldings and seeing what can be crammed in, like the dreadfull Rhino I once owned.
I also feel that Matt is a good guy to deal with, and aftersales service and back up is important when cosidering any major purchase. He gave me a lot of time a couple of years back when I was looking for a machine, with no hard sell or pressure to buy, and continued to be very supportive despite me buying elsewhere on that occasion.
I would add that I have no affiliation with Cleansmart, they are only one of many companys I deal with, I just speak as I find, and I have found the Airflex to be, so far, a really good buy.
