This is a generic type of cutter. Mainly its only the brand name that differs.
I had a similar one a while ago and it did the job but the pump was prone to not working..very easily clogged. I would drop the pump in a bucket of water.
The power wasnt too good either when cutting travertine. porcelain nd marble but ok for normal stuff...but then i wouldnt use it for ceramics !
IMO its ok and not far off the Rubi
standard although the Rubi has a better motor.
Oh and the size has limitations too, you wont get a 600mm
tile in there !
