I love this flat iron. My previous iron was expensive and I was willing to spend the money again. But after reading several reviews for several brands, I decided this sounded just as good as the expensive ones. I have thin hair, but lots of it! When I blow dry, if I don't use a roll brush, will flip outwards in a couple spots. This iron works really great on those spots. I like it gets up to 450 degrees. That really helps, also.

Secondly, I wish it would remember the heat setting. Every time you turn it on, you have to change it from the default setting.

I am a person with wavy hair. With this straightener I can make them straight in few moments. It is heating up in seconds to the temperature you choose with bottoms on the side. After using it my hair are smooth straight and they’re stay like this for hours.

Best hair straightener I've ever owned, and I've tried a lot. I used to have a Chi and some other pricey straightener and this works way better for less money. I don't buy a hair straightener that doesn't have heat temperature controls or levels, as some do not get hot enough to do anything! This tool has four levels for heat options. This is the perfect width if you have long hair like I do. You don't have to run multiple passes over your hair which can damage your hair. I am planning on buying another Remmington if it ever fails on me, but I have had it for 6 years!

I love this straightener,i tried a few other before and none of them works this great! It has a safety button on the bottom and bottoms to set the temperature up and down also turn it off and on. The design is beautiful. Thanks to the keratin treatment my hair is beautiful and shiny,also very quick to straighten it and leaves the hair straight for day.

When I️ first got this straightener I️ though it was the best one I️ ever had. Then as a couple months went by I️ could see it going down hill as it would begin to not keep a constant heat. And eventually it started to shut off once it would get hot. And even shut of randomly. I️ would get another one because of the good experience I️ had while it was actually working and the price isn’t horrible. Over all I️ would rate it “ good while it lasted” type of deal. The lock feature for the heat is good because my fingers would always slide and change the heat. And the lock on the straighter itself was handy to keep it closed for storage. Not a bad straightener, it didn’t pull on single hairs and made straightening quick and painless. Not a bad product!

Excellent value for money. It heats up quickly and, unlike some other irons I know, this Remington really fills your hair with keratin. The result is better protection and longer results. Heats up quickly, easy to handle and modern design. Automatic shutdown function. If you are looking for the best hair straightener that is just perfect for your strands, but is overwhelmed by the variety of products available on the market today, then I recommend REMINGTON.4 stars only because a faint smell is reported for a few days.

Love this iron
9 April 2017

I never write reviews but I feel compelled to let all those who are looking for the perfect flat iron to look no more. In the last month I have purchased 4 very expensive flat irons and returned them because they all snagged my hair. I have long thick hair. When I went back to Ultra to return yet another flat iron I spoke with a sales person who suggested this one. I was a little ambivalent because of the cheaper price and it wasn't one of the higher priced, higher end products. I am one of those who "thinks" the more expensive, the better the product. Well that is not true in this case. This iron does NOT snag. It is smooth and glides right through my hair leaving it very shinny. For those with longer hair, you can even add a curl at the end. It has a sensor that ... MoreI never write reviews but I feel compelled to let all those who are looking for the perfect flat iron to look no more.

It has a sensor that detects if the temperature is to hot for your hair and it will readjust the temperature according. I can't say enough about how much I love this iron. I am so happy the sales girl recommended this to me. I had in my hand and about to purchase another CHI in hopes it would be the one to not snag. I am glad I didn't get it. Search no more. This is your iron.

Saved my hair from previous straightener iron
2 June 2024

I used to own a GHD iron and it literally killed my thin hair even tho I was using heat protection.There were flat and without shine. I switched to this one and my hair are much healthier, voluminous and less thin.I use it once a week at lowest temperature and with heat protection.

Everybody knows straightening damages your hair and leads to dry brittle hair with split ends, so to have a set of straighteners that are good for your hair is Holy Grail for manufactures.The packaging is clear and displays all the benefits of the straighteners; the box its self is silky and smooth, a sign of things to come, perhaps. In the box are the straighteners, instructions and a quilted heat protective pouch. The pouch itself has a Velcro tab for you to secure the straighteners in place, an integrated inner pouch for you to store the wire neatly when not in use and a magnetic stud close. The inclusion of a heat protective pouch is a great idea so you have a protective surface to put your straighteners on while you are using them and you can put them in the pouch immediately after use so they are safely out of the way. The instructions offer guidance and recommendations for hair type (density) and how best to use them.The straightener’s ergonomics feel comfortable in your hand; the cord is of a good length and swivels to prevent damage during use. The ability to lock the plates prevents damage to the straighteners during every day use and also means that they can be made safe immediately after use. The plates are of a good length and width to make straightening more efficient and the floating plate gives smooth even straightening. The bottom half of the straighteners are matt black with the upper half in a light gold colour. The top of the straighteners has a nice touch with an integrated digital display; symbols glow white through the handle when you switch the straighteners on showing the heat protection sensor and the five heat setting icons, making them easy to see in low light conditions. There is also an automatic shut off function if a button is not pressed during a sixty minute period which is a good safety precaution.During use the straighteners heat up quickly and the five adjustable heat settings are useful for different hair types and densities. The ability to lock the temperature, turn off the heat protection sensor and have a heat boost will appeal to hairdressers who know how to compensate in speed and section thickness during straightening. I straightened one side of a client’s hair with my straighteners and the other with the Keratin straighteners; while there was not a lot of difference between the two during use the side straightened with the keratin straighteners was definitely smoother, shinier and more compressed.As a professional I like them, they are kinder to the hair, leaving it looking healthy, they have some great functions, and come with a reassuring five year warranty. My only concern is how long will the Keratin stay infused in the plates? I’ve only had them for a week and so far I’ve been impressed with their performance and easily see me continuing to use these as soon as I retire my straighteners. They’re not the prettiest set of straighteners I’ve seen (the Remington Pearl was certainly more attractive) and to some extent I feel Remington may have missed a trick with these.

Stopped working after 3 months
8 May 2016

For the first few months, I really enjoyed using this flat iron. After daily use for about two months, it stopped being very effective. I realized that it was shutting off and making a crackling sound as I ran it through my hair. It seems that there's some short in the swivel on the cord, and as I give my wrist a slight twist towards the end of my hair to bring a slight curl to the end, the iron would short out and shut off. To top it off, after it has shut itself down a couple times, it won't turn back on until the iron is completely cooled. (So yep, I definitely had to go to work with half-styled hair a few times.) It does heat up fairly quickly and was otherwise a good purchase for the price, but since it doesn't have a warranty there's nothing I can do to ... MoreFor the first few months, I really enjoyed using this flat iron.

I'm able to use it for a couple minutes to straighten out the kinks left at my temples when my hair dries, but there's no major styling that I can get out of it anymore. Perhaps I just had a defective model, but without a warranty on it I don't recommend risking it. Save your money for something else.
