"For the size it works well and I like the ability to adjust the heat settings. The effort it takes to close the iron on the hair is a little more than I'm used to and it's heavy. Straightens my hair quickly but not great for putting in a wave like when I use my narrower iron. Not sure it's worth the money. May be better for thicker hair."
"I love this, works so well, heats up fast, makes my life easy. So worth it !"
"The name of this product is sooo accurate. My old flat irons could not make my hair as straight and sleek as the Bioionic one does. Straightening my hair is a breeze now!"
"These flat irons are awesome. They get hot very fast and work effectively. My hair was soft and shiny after using these flat irons."
"I bought the flat iron from my daughter and she absolutely loves it. states it works great with her long hair."
"Love this straightener!"
"Es muy buena plancha pero pesa demasiado"
"Unless I got a lemon, the quality has decreased since I bought my last One Pass in 2014 or 2015 which is very disappointing considering the price. The silicone strips are supposed to prevent hair from getting caught, but I've changed my technique to see if it's user error and it is not. I have fine hair and have a lot of it and use the recommended temp settings for my hair type."
"I was sooo hoping to love it. I did a lot of research because I was willing to spend more for a quality product. Bio Ionic seemed to have great reviews, quality product , specific mechanics, so I jumped on a sale they had. While all of those factors may still be true, the model I bought seems clunky and difficult to navigate despite having 3 buttons. ha! user error perhaps. I can’t speak to how well it worked because i decided to return it. I had buyers remorse despite it being a pretty good deal! I’m mid 40s and my hair has recently become very brittle and dry. so it’s a bit of a sore subject for me, at no fault of theirs. My life story and a review"
"Since I keep getting prompted to leave a review, here goes. My last One Pass lasted me over 10 years but recently kicked the bucket. I bought another brand but it simply was not the same quality I was used to with Bio Ionic, so I caved and bought another One Pass. To my surprise, the little silicone strips pull my fine hair quite a bit more than they did with my previous model. Glad to have bought this while on sale, but definitely not super satisfied."
