It's hard to use solo to some extent. My hair has gotten caught in it a few times but I found if I reduced the amount of hair that doesn't happen (I personally didn't think it was a lot of hair but the machine feels otherwise). Since you have to use smaller amounts of hair it takes longer to curl mid-length hair. It makes great spirals though! Definitely use the higher heat settings if you want tighter curls. Also, watch a YouTube video to help with tips on how to do your hair by yourself!
I had to practice a little bit, but I really like it My hair doesn't hold a curl well and is really fine, but it does much better with this tool than any I have fine And the price couldn't be beat! I got the professional tool for 10 dollars more than what I could have gotten the cheaper version on the "Black Friday" Sale price Wow!
