I have been using a Genesis portable cutter for years but I had to get a new one today as although the cutter still works, the rubber seal from behind the blade just got too old and crumbled off. Shame I love that cutter... but I replaced with a... ...Vitrex from topps at £99.99 (i needed it urgenty, as the old one is now too riskey to use).
With the induction motor and 750w it cut through 45x45 porcelain (metal finish) like a knife to butter and you can apply good pressure if you need it.
It is also quiter than my last one. Externaly it looks just like the big Plusplug cutter.
I think this is goin to be a winner (for domestic work) and it does not splash water everywhere!
