I had a polti  years ago but I had to wait for it to depressurise before I could refill it so I bought a Tefal one which has a detachable tank and its great, I would never use a normal steam iron again, they are especially good for pressing heavy denim and if you need to iron large things like curtains or duvet covers they are excellent as they cut through creases like a hot knife through butter, they are especially good for awkward materials like linen, once you get one you too will not go back to an ordinary iron as they cut down the time by at least half.
