Review: Great product! - This works so incredibly well! I had been wearingy hair curly for years. I decided to go the straight route. I read all the reviews and chose this t3 product. There's a good reason they call it single pass. My hair is shiny. Bouncy and straight! Review: Truly works in a single pass! - I just received this flat iron today and just used it… I don’t think I have EVER had a flat iron truly work on the first pass. I have thick, fine hair and straightening it is time consuming. But this flat iron worked amazingly! Very happy and I highly recommend it!

Poor Customer Service
As a professional I depend on my tools to work and at this price point I expect some longevity. This flat iron stopped working after 8 months. I reached out to T3 customer support to file a warranty claim. After waiting weeks for a response, my claim was approved. Now months later I have not received my replacement. This is extremely disappointing and I will not be ordering any more tools from this company.

On/Off button got stuck and no longer works.
I purchased this in October 2024 so I haven’t even had it a year and a half. The on/off button that you push in to turn on, is stuck in the ‘pushed in’ position. I’ve tried everything to release the bottom to no avail. I will say that it worked wonderfully for my course, naturally wavy hair during the time it worked, but since I only use it a few times a week, at this higher price point I expected it to last longer. Alas I will not buy this again.

No evidence of frizzy hair after this one pass flat iron
Because of overprocessing my hair, it looked frizzy after blow drying it. I wanted a sleek look with smooth ends. This flat iron has done the trick. My hair looks shiny, sleek and smooth after usage of this flat iron.

Highly recommended
This is an excellent product for the price. Highly recommend. Multiple heat settings, easy to use and maneuver handle, the thickness of the flat irons is perfect for short, medium and long hair. It looks sleek and very high end, comes in a great packaging and very durable itself. The long electric cord makes it really easy to work with.

Snags hair
It’s ok. It does the job. The other reviews about it snagging your hair are true. I just have to go really slow and it helps a little.

Chauffe rapide et résultats professionnels
J’utilise ce fer à lisser depuis plusieurs mois maintenant et il fonctionne toujours aussi bien. Il chauffe en quelques secondes seulement, ce qui est très pratique le matin quand on est pressée. Je n’ai pas remarqué d’accrochage ni de dommages visibles après plusieurs utilisations. La température semble stable et constante. Très satisfaite de la qualité et des performances. Excellent achat.

Best Hair Straightener I’ve Ever Used
Hands down the best hair straightener I’ve ever used—definitely worth the price. The quality is excellent, it heats evenly, glides smoothly, and leaves my hair sleek without feeling dry or damaged. I’ve noticed less breakage compared to others I’ve tried. When it’s time to replace it, I’ll absolutely be buying this one again.
