After reading threads on steam rollers, I was really psyched and yesterday, I purchased the Caruso Steam Rollers. As directed, I put the water in it and plugged it in. I barely saw any steam. When I put a roller on the steam spout, the roller did not feel warm or anything. I think I purchased a lemon. Is there supposed to be a lot of steam coming out of the spout and how is the roller supposed to feel? Thanks.
