The Rowenta's have known issues with starting fires. Sparking up, etc. I saw a nice reviews for an Oliso, but I like the Shark I have. It is heavy but works well.
I had an issue with it not steaming if the water tank is more than half empty. Called Shark and they sent another one. Was actually another company... Europro, I think. I tried to find the post to give you the model but I type way too much ...
Oh, I found the email model R5704179-01
