SINGLEPASS X is rated 4.6 out of 5 by 50.
Rated 3 out of 5 by from it's okay I used it for the first time and I had at least 10 pieces of hair get caught at the end of the plate where there's some space. It didn't leave my hair feeling protected like my other straightener. I'm really sad about it, because I was soo excited when I ordered it. I think I'm going back to my old straightener. The temp was good on it, and it is pretty.

Rated 4 out of 5 by from T3 singlepass I have really unruly, curly, frizzy hair and this does a great job in making my hair sleek straight. For when I originally straighten my hair after blow drying I use it on the highest setting, but after that for touch ups I use the lower ones. It leaves a great shine and helps tame those fly always. The only reason this didn't get 5 stars is because I was hoping it would reduce my style time, but unfortunately it takes the same amount of time as my 1 inch cortex straightener. However it does do a better job of straightening more throughly and the tourmaline plates definitely make a difference. I would recommend this product for people with curly hair.

Rated 5 out of 5 by from Great buy! I lucked up with this purchase. I won't guarantee it's truly a single pass, but it definitely works leaving my hair feeling smoother looking shinier than my last flatiron.

Rated 5 out of 5 by from Got me hooked on T3! This was my first T3 product that I ever purchased and I'm not kidding when I say this got my hooked! I have bought plenty of styling tools before and nothing has compared. I feel like I'm actually helping my hair when I use this straightener. My hair is wavy and frizzy naturally and my hair always looks so smooth after using this!

Rated 5 out of 5 by from Best Straightener!!! After doing my research, I debated if I should get this one or the T3 compact straightener. I originally bought the T3 compact straightener thinking I would save money by buying the smaller one. However, due to the fact that I have long, thick, coarse, straight, coloured hair, I found the T3 compact straightener to be too small for my everyday needs. So, instead I exchanged it for the T3 SinglePass X 1.5" straightener. After my first time using this tool, I fell in love. The T3 SinglePass X 1.5' straightener works amazingly well with my hair. The straightener is light, easy to use, and fast to use. The heat controls are smart, and is evenly distributed within the plates. It doesn't fry out my hair like my old straightener. I also like how I can create bigger curls with this straightener. In my opinion, this tool is of high quality standard.

Rated 5 out of 5 by from BEST THING THUS FAR I LOVE this product. I have very difficult hair and live in the desert so when and if I ATTEMPT to straighten it or anything, normally I'd spend AT LEAST 2 hours and a million different products just to get fried, greasy looking hair. But with this I only take maybe a half hour and one product with no straw head! ❤❤❤❤❤It

Rated 5 out of 5 by from no better flat iron or brand for that matter! I purchased this at ulta literally based on the price. It was the most expensive so it had to be the best right? Well it has now been 2 years since that date & my hair is so healthy. I bring it with me to my salon & insist nothing but T3 get used on my hair! I also got the blow dryer & my hair really feels better after using the blow dryer & flat iron vs. Allowing my hair to air dry! (which with the T3 blow dryer seldom areas need touching) the products are made very well. I have dropped mine so many times by mistake & still not a problem (now I don't abuse my stuff but I do have clumsy moments)

Rated 5 out of 5 by from Lady K Love the 1.5 Single Pass Flat Iron! I've never owned a Flat Iron and decided to splurge. Was Soooo Worth It!! Flat iron was easy, one pass as stated, heats up quickly. The only thing I Would consider changing is placement if heat setting which can be easily bumped/changed while using. You deserve it Ladies, Go ahead and Splurge on yourself, Worth every $$$!! I am now considering buying the Making Waves set granted it is back in stock soon at the same $350 sale price. You will Love this Flat Iron!!

Rated 5 out of 5 by from Skeptical but sold I always thought a flat iron was a flat iron. I'd go to the local Wall Mart and never pay over $20.00 because to me it was alot it money for just a "flat iron". Well that's not the case. My daughter told me about the T3. I had to try it. I bought the $180.00 one. I used it one day and quickly turned around and bought the X. $210.00 more than I have ever paid for any flat iron. I've never regret ed the purchase. My hair is finally in great shape. I highly recommend this product.
