"I've known this straightener since my apprenticeship at the hairdresser. I've compared it with countless other straighteners, but in my opinion, the Tondeo straightener is the best ! The straightness stays even in high humidity or rain – no bounce, no frizz! The curls last a long time and look beautiful. For this price: a real gift ."

A. Pfeiffer, Amazon review
"The straightening and curling iron feels very high-quality and fits comfortably in the hand. The three-meter-long cable offers sufficient freedom of movement, which I personally find very important. The six temperature settings allow for individual use – although it would be even better if the temperature could be adjusted freely. My test subjects confirmed that the device is good and easy to use, and the results are very convincing . Overall, I am very satisfied and give it five stars."

Stevie, Amazon review
"Very good straightener. I bought it because my hairdresser uses it. It straightens hair perfectly and also creates curls quickly and easily. You can adjust the temperature to your liking, and it's very high quality . I would buy it again ."

Rani, review on Amazon
"I can only recommend this straightener .
I have very thick, naturally curly, and therefore dry hair. With this iron, you can actually create beautifully defined curls as well as a smooth look (without the "straw" look).
It took a few practice attempts until I got the right amount of hair. The strands can be sectioned off normally, so you can finish the hairstyle relatively quickly."

H. Wiener, Amazon review
"The straightening and curling iron arrived well packaged. It's superbly crafted , robust, and appears to be of very high quality.
It heats up very quickly and is therefore ready for use very quickly . You can use it to either straighten your hair beautifully or create waves—both work great once you get the hang of it.
The price/performance ratio is ok and I can definitely recommend it. "

Clean the styling plates regularly with a slightly damp cloth to remove any styling product residue. Be sure to protect the straightener from bumps and drops. Allow it to cool completely after use and store it in a dry place to ensure the device stays in perfect working order for a long time.
