I've used this for quite a while, but it's difficult for my children to use, so I'm selling it because I bought something else. There are no noticeable stains, but the switch for converting between straight and curl has become loose due to aging, and sometimes it will switch to curl mode on its own when used for straight styling. There are no disconnections, so I think it can still be used. ☆I found the instruction manual, so I can include it☆
