"I absolutely love my SMART-X™ High Efficiency Dryer + Diffuser! It is unlike any I have ever owned before! It is made of quality materials and dries my hair very quickly and leaves my hair in better condition than other hair dryers have in the past! The BIO: IONIC warranty is also much better than any I have seen in the market! This is a new dimension of hair dryers from years past—and is well worth what you pay for it!"
"I love my hair dryer. It’s definitely a game changer when drying my hair. It’s so much faster and leaves my hair shiny. I was very upset when it stopped blowing warm air but I was able to send it back and receive a replacement. I wasn’t happy about having to pay $33 to ship it back but was pleased with the quick shipment of a new one. I highly recommend The smart x hairdryer. My daughter loves hers too!"
"The Bio Ionic SMART-X™ High Efficiency Dryer + Diffuser is hands down the best blow dryer I've ever owned! It's super lightweight, has three different speed and temperature settings, and even has a lock button so you don't accidentally change the settings while drying. It dries my hair incredibly quickly, and my hair feels healthier and less damaged compared to when I've used other blow dryers. Bio Ionic's customer service is phenomenal, and they truly stand behind their products and warranties. I recently had an issue with my previous dryer, and they sent me a replacement incredibly quickly. If you're debating whether it's worth the investment, BUY IT! You won't regret it!"
"My hairdresser uses this brand. I bought for a lighter weight dryer for a senior citizen. Also my hair is getting coarse and brittle, this has helped."
"Honestly, everything happened very quickly; the replacement arrived in record time, and I highly recommend the brand. I was very satisfied, thanks a lot!!"
"I received my first dryer December 2025, i cleaned the filter about once a week, it got super loud and weak out of no where in April/may until it stopped working completely, i used my warranty and got a new one in June, i got my new one very fast after mailing out my broken one, i am a hair dresser and specialize in blowouts, so i made sure i was cleaning my new one every day I would do the self clean with a little brush and I would scrub the part that came off as needed, my new dryer got super loud again in September and 2 weeks later the heat stopped working completely, I loved this product but it did not hold up, this not durable for a stylist use. I would like to use my warranty and get a new one again but I have not had the time to mail it out and i no longer trust this product as a stylist I can’t worry about my hair dryer breaking If I decide or have the time to mail my broken product out I will be using it personally, not at the salon, disappointed because I did love this when it worked."
"It doesn’t deserve even one star. Hairdryer broke within 4 months using it and 10 year warranty is a joke. I sent them blow dryer for my money and they just sent email that my warranty is denied. Please beware!!! My colleague sent hers 6 times and her last one broke again!"
"I love this blow dryer! I work behind the chair and run a 6 figure solo business, this is my most used tool. It’s lightweight, quiet and a power house! The warranty is great and it was honored when I sent in my blow dryer when the heat unit went out. It took about 10 days for me to make a claim and get it back. I highly recommend this blow dryer!!"
"Love this dryer. It's nice and lightweight. It gets HOT and it's not loud...yay"
"This is the 3rd Smart-X High Efficiency Dryer I've owned. I originally purchased it because of style, color and light weight for travel purposes. I have medium thickness shoulder length hair that is kind of course. This dryer has the right amount of temperature and fan that it doesn't dry my hair out like other brands I tried such as the Shark. I do have to say it has a design flaw in the motor, which gives it usage life of 1 to 1.5 years. Unfortunately, I forgot to register the product and ended up having to rebuy my 2nd one. This time, I did complete the warrenty process. After one year from purchase, the same issue occured, the only thing that would work was the cold function. Apparently it's a design flaw in the motor and it's a safety issue that switches it to cool shot only. There is no turning off and letting it cool down, it just gets stuck in the cool function mode. I did submit a claim and was sent a brand new Smart X High Efficiency Dryer. I do have to place on calendar a note to purchase a back-up hair dryer, probably a different Bio Ionic one so that when mine stops working, I can send it in for warrenty claim. I wish the design flaw could be corrected as it's the perfect hairdryer for me, including how light it is for traveling."
