B E S T CURLING IRON!
I would give 20 stars if I could! Best curling iron ever! Coming from someone who did hair, it is hard to find a curling iron that holds the hair tight, but still lets it barely be opened enough to slide and perfect the curl. Long barrel keeps hair from sliding out while trying to spin it. Heating level even on the third level is great. It's beautiful and is definitely worth the money. The part that is in your hand is made of good quality satin material that allows you to hold with ease all while spinning. The size of the barrel and the part in your hand in just the right size and will not make your hand cramp and it doesn't slide in your hand while you spin.

Recommend for thicker hair
Heats up very quickly. Very wide, so best for long hair. I would also recommend for thicker hair. It is extremely powerful but the curls still don't stay for long in my thin hair. Very nice quality but also no resting clip, so it sits on whatever surface it's on, so keep on a safe surface.

Wow
Finally. I vowed to give up curling irons due to damage to my hair, but the costly air styler roller tools did not work well for me. I searched for a curling wand that was ceramic (check) had precise and varied temperature settings (check) and was reasonably priced (got this on sale). I am so happy with this product. I set it on level 4 (320 F) and it styled perfect curls and waves in my thick, coarse, hair which are holding beautifully. The nine settings range from 260 F to 410 F. The accompanying product info booklet lists the precise temperature settings which enabled me to select a precise low heat to prevent damage. I'm going to go even lower next time to see if it will still deliver these fantastic results. There is a 2 year warranty. There is an offer of an additional year of warranty if you register the product. I am so happy to find this product and hope switching from my old curling iron to this one will enable me to maintain healthy hair. I highly recommend this product. Well worth the cost. I really wish they would make an airstyling tool for medium to short hair (smaller diameter rollers or brush). Meanwhile, I'm going to stick with this more traditional curling tool for a polished look that holds up.

3 months in — still impressed
As someone who has gone through many curlers, here’s my take on the T3. I’ve had it for about 3 months and it’s safe to say that the quality is definitely there. This curler is not flimsy, it’s premium quality. I love the size I choose for the curls. I’ve used this product with thick extensions and without extensions and both curls hold up nicely. Takes less than 2 minutes to be ready to use. It’s easy to use, but I have to say this curler is a bit heavy. That is why I’m giving 4 stars.

Love this iron
With this price tag, I hope it lasts. I have been using curling irons for decades, and have tried Revlon (hinge snagged my hair), Conair (new one is flimsy and doesn’t heat up enough compared to the one from my teens), TAIFF Curves (single fixed heat setting wasn’t hot enough for my stiff hair), CHI Spin and Curl (couldn’t capture the ends of my longer hair), L’Ange Airflow (get frizzy curls), and Bio Ionic (kept accidentally hitting the buttons on the handle during use). Most recently, I’ve been using Hot Tools, which gives me perfect curls, but got tired of that soft touch TPE coating degrading after a few years and turning the handle into a sticky mess. The spring on my most recent purchase broke after 4 months. After so many fails, this no longer seemed like an expensive option. Pros: 1) I love the extra long barrel. 2) Clasp is tight and grasps the entire bundle of hair. Nothing slips out. 3) Hinge is really well designed and doesn’t snag hair. The opening and closing motion is very smooth. 4) The blush color is really pretty. 5) It has a very long cord. 6) There is no soft touch TPE handle. 7) The highest setting is really hot. I have stiff straight hair, so I need high heat for my hair to hold a curl. Cons: 1) Oof, it’s heavy. However, this works well enough that it takes less time to get my whole head of hair curled, so the weight isn’t an issue for me. 2) There is no kickstand, so the iron is close to the counter when you set it down. It’s something a silicon mat will solve. 3) The inconsistent reviews on longevity is a concern at this price point. If this lasts, it’s the best iron I have ever owned. I like it so much, I ordered the 1.5 inch as well. I didn’t want the 3-barrel interchangeable set because I like having an extra long barrel.

Works well

Smooth fast curls
I had an old T3 model that was still working but I wanted to upgrade. Big difference! Longer barrel, fast heating and the smooth ceramic left my curls noticeably shinier and smoother than the old model (I think it was a teflon non-stick barrel). Happy I got this.

Me mandaron usado el producto
El producto que recibí presentaba señales de uso, lo cual afecta la experiencia general. En cuanto al funcionamiento, la tenaza, pero la primera impresión no fue la esperada. El desempeño es bueno, aunque por la condición en la que llegó no puedo evaluarla completamente como un producto nuevo. Considero importante que la calidad coincida con lo que se espera de este tipo de artículo.

Great results on every hair type
I purchased the T3 SinglePass Curl X Extra-Long Barrel Curling Iron after looking for a high-quality styling tool that could work efficiently on longer hair and deliver consistent results. First impression, the build quality is excellent. It feels premium but still lightweight and easy to handle, which makes styling more comfortable, especially when working through the back sections of hair. The extra-long barrel is a standout feature — it really does speed up styling because you can work with larger sections and reduce the number of passes needed. The 9 heat settings are very useful and allow for better control depending on hair type and styling needs. Heat distribution feels even across the barrel, which helps create consistent curls without hot spots or uneven sections. In terms of performance, I have thin hair and it worked beautifully for me. It created smooth, soft curls without making my hair feel overly dry or damaged. The finish looked polished but still natural, which I really liked. It also worked really well on my daughter’s 2C–3C curls. It helped define her hair and created soft, long-lasting waves without making her hair feel overly stiff or frizzy when used with proper heat protection. It performed consistently across both of our very different hair types, which was impressive. Overall, this is a high-quality curling iron that feels well-designed and reliable. It delivers fast, even styling and works across multiple hair textures. While it is definitely an investment, the performance and versatility make it feel worth it.

Would recommend
Very nice, expensive but also feels and looks expensive compared to many others, the hair can slip out at times but easy to learn how to use. The buttons are a little confusing but easy to use, very pretty colorway

Love this curling iron
I bought 3 of these as Christmas gifts and everyone loves them. Just be careful when using because it has several settings and the highest one will definitely burn your hair and skin if you’re not careful (yes, this happened to me)! Works great!
