Rated 5 out of 5 by from As usual with T3, this As usual with T3, this product is great. Got it to interchange with a clip barrel for when I want a messier look. Still mastering the technique, but it's far easier to use than I imagined!

Rated 5 out of 5 by from perfection I recently got this in a package and I have been using it non stop. I had other curling irons but none can top this one. I love the curls it makes. my hair usually does not stay curled until the evening but after i curled it with this it lasted even until the next day. I absolutely love this!

Rated 4 out of 5 by from Good Curling Iron I think this is a great iron, and I love how the barrels are interchangeable. It heats up quick and evenly. I docked 1 star for price. I can't say I notice that much difference between the T3 vs another curling iron I own in the $30 range.

Rated 5 out of 5 by from Ideal curls This 1 inch curling iron attachment is great! I bought this after the hair stylist who did my wedding Hair recommended it! I do allow my curls to loosen a little with gravity after using this curling iron though.

Rated 5 out of 5 by from Prefect curl every time I love the curl this barrel makes! It is absolutely gorgeous! I own three barrels so far and this is probably my favorite! My favorite way to use it is wrapping the curl starting about 1-2 inches from my head and leaving 1-2 inches at the ends of my hair so only the middle curls. It provides such a beautiful waved/curl look to the hair and because the ends are left straight you can really see the separation in my layers.

Rated 5 out of 5 by from Perfect This wand is perfect! It makes even size waves all around my hair, and when I want them looser I just tug on the curled section lightly. Plus the waves last a few days even without products. (with the exception of a heat protectant) My hair is mostly straight and thick, length is below the bra line.

Rated 5 out of 5 by from Tighter waves I love using this barrel for a tighter wave. Once I wrap my hair around the wand I tug a little to loosen it a little!

Rated 5 out of 5 by from Easy to use! This a great barrel! It came with me 'Making Waves' gift set that I had purchased. I love clip-less curlers because I feel that it is easier for me to use them. This does a great job and it's super easy to use. The curls turn out really good and my hair doesn't feel fried afterwards. This is definitely one of my go tos!

Rated 5 out of 5 by from Love! This is my first curling wand I've ever owned and I'm so impressed! I also bought the convertible base. I have fine hair that I used to think couldn't hold a curl well, but my curls with this wand lasted into the second day. And they were so shiny!
