Great for the price
Nice straighteners. They heat up fairly quickly and have 3 heat settings so suitable for all hair types. They came with a heat mat which is a bonus as thats something I always forget to buy. Only alight negative for me is they felt quite bulky. This may be because i have a pixie cut, but I found it quite hard to get to my roots.

Cosmos Styler - stylish and effective
The straightener has been a great addition to my routine. The build feels durable and high-quality,it heats up quickly which is perfect when I am in a rush, and it’s extremely easy to use. The design has a lovely colour that looks great on my vanity. It offers three heat settings and on/off button on one side which keeps things simple, however the downside is that I sometimes press the buttons accidentally while styling. The 2 meter cord is a practical length and gives enough freedom to move around, though it does feel a bit rigid especially when trying to create curls. It’s doable but not graceful :). It comes with a heat mat, that is useful touch for protecting surfaces. Overall, I like this straightener. It’s fast, reliable, feels well-made and delivers good results.

Lightweight and compact
This straighteners are light weight and compact. Cord is a good length. They heat up quite quick. The protective mat is very good. They straighten my hair lovely , I’ve got fine hair. The only other thing which would be handy with these would if they could supply a glove so you don’t burn your hand.

Excellent Straightener
Excellent great value for money. Smart design comes with 3 different temperatures heats up very quickly. Also comes with a heat protection pad to leave the straightener on. Very light straightener leaves hair very soft.

Great for curling hair
These are really good straighteners! Love the curve on the plates which mean if you’re curling your hair you don’t get the dreaded boxy bit which you often get with normal straighteners! My hair struggles to hold a curl but held these really well. Only thing is there’s only 3 heat settings.

Works well
I like this hair straightener because it's lightweight, easy to use and it leaves the hair looking smooth and sleek. It has 3 levels of heating (low, medium and high) so if the hair are coarse then we can use the maximum heat to straighten them up. If the hair are thin and weak then minumim heat would be required. For normal hair type the medium heat will be okay. This straightener doesnt have locking mechanizm but instead we receive special heat proof mat that we can reat this hot straightener until it cools down after use. Then we can simply wrap it up with that mat for safe storage and protection. I can recommend this product because it's good quality and looks pretty too.

Good straightener.
Really nice hair straightener. Nice and smooth. Doesn’t pull on your hair as you straighten it. Heats up quite quickly too. Only reason I didn’t give 5 stars is that I wish it had was manual temperature settings. Still a very good product.

Silky smooth *ZERO SNAGGING* easy to use!
Good cord length on these so i dont have to get an extension cord out just to style my hair. Very simple to use - low heat setting = green, mid heat setting = orange and high heat setting = red - these can be altered by pushing the standby button - the only downside is not knowing what temperature these are set at - my hair is highlighted blonde so i tried the low setting first then opted for the mid heat. Theres absolutely ZERO snagging when running these over the hair is glides effortlessly leaving my hair silky smooth and with a healthy shine that doesnt feel damaged from the heat. They heat up in about 20 seconds and come with a handy heat mat so you have somewhere to lay them between styling and when youre finished. I havent attempted to curl my hair with them as my hair is quite short but judging by the round edges of the straightener i would have no problem achieving perfect curls. The way these have left my hair feeling are definitely on par with my more expensive straighteners - my ☁️ 9 (unsure if I'm able to name drop other brands) so it will be interesting to see if they have the same lofe span as those as ive had them over 10 years and they still work perfectly!

It’s ok, a little on the small side
My old hair straightener had packed up and I had great expectations for this one, it looked nice and promised shiny hair. I have to say however , I’m not overly impressed after the first uses, the ceramic plates are quite small, so would probably be best suited for when travelling or for short hair, my hair is medium long and thick and I felt I couldn’t get enough of it and had to take long time to straighten it. I am also not keen on the location of the heat buttons, I kept hitting them while straightening my hair so the heat setting kept changing. It’s ok but there’s better on the market.

Sleek and smooth hair
I love these straighteners, they are light weight and super smooth on my hair. I have really thick long hair and my old straighteners would always leave it still frizzy. These are so sleek and light weight to use. It’s much quicker to do my hair. The wire spins around the bottom with the straighteners meaning it moves easier when you are straightening all your hair. The design is lovely, I love the colour and overall appearance. The controls are easy to use and it has variable heat and it is hot enough to handle my thick hair and leave it looking lovely and shiny. I’m really pleased with them and it comes with a protective mat to place them on that can be wrapped around once you have finished using them. I would definitely recommend these straighteners to others, BaByliss is definitely a brand you can trust and they are better than a more expensive brand that I had previously used.
