Rated 3 out of 5 by from Bio ionic one pass Read the reviews, before I purchased, you really only need one pass, but I don't like the plates, don't glide smoothly, wish I could return them, but of course, I can not, I really wanted to like them.

Rated 5 out of 5 by from Best Straightner I have Ever Owned! Absolutely the best straightener ever! I can curl my hair with it or straighten it and people say it looks like I've had a brazillian blow out.

Rated 5 out of 5 by from Who could be happy their iron broke? Totally ME!! I accidentally dropped my last one and it broke. I go the new bio- ionic one pass to replace it and it is the BEST iron I have ever used. And I don’t go cheap. love the size, it fits so well in my hand, it doesn’t pull the hair and leaves a beautiful finish. I could only be happier if it turned off after 30 min if I forget. But I love this iron!

Rated 5 out of 5 by from LOVE THIS I truly love this flat iron. It glides through the hair with pulling it, and It produces beautiful curls. I am not disappointed on my purchase at all. Also, I did get this on sale. I feel like I got a great deal on a product that I would have paid full price for!

Rated 5 out of 5 by from Great flat iron! I have had two of these irons now and they are great for smoothing! They grip well to to get that extra smooth hair. Only negative is you can’t use them when doing keratin treatments. The bands on the iron stick to the keratin.

Rated 2 out of 5 by from Keep breaking I have had 4 of these now. I really want to like it but they keep breaking. I've had the silicone speed strips deteriorate on every single one. Two of them now have developed shorts in the cords and stopped working. The warranty basically does not cover anything on it. I really want to like this flat iron because when it does work it is amazing but the quality just is not there. As a stylist I need something more dependable.
