I have a Saphire, I've had it nearly four years and yes it did take some time to get used to it, I used a hell of a lot of water in the early days, the sheardry is very similar but cleans much faster, the only problem at the mo, it spits a bit through two forward and two rear jets, Chris is trying to get the problem rectified
With rotavac, but I am very glad that I bought it, ive had it four days now and have cleaned six suites, cant see me going back to the Saphire in a hurry
