I bought the Shark professional about 9months ago. I LOVE IT! I am pretty rough on irons but this one seems to be able to take all I can dish out. I love the auto shut down because I have been known to forget to turn them off-but I hate the auto shut down when it goes off while I am still working. LOL I have dropped it a few times and the dog knocked the whole ironing board and iron over one day chasing her ball.......still works great.
