Anyone use a Rotozip RZ3 or RZ5

[Micci]

Hi'ya,
Does anyone use either the Rotozip RZ3 or 5 for cutting tiles ?
I was thinking of investing in a Spiral Saw for cutting tiles and wondered if anyone used them for this purpose, with a dedicated drill bit of course.
I have seen thin'ish wall tiles cut with one but unsure about thicker floor tiles.
