And while celebrity beauty recommendations are a dime a dozen, this one has an extra practical selling point: the curling iron is designed to do much of the work for you.

Priced at $139.99 on Amazon Australia, the TYMO CurlPro Plus is an automatic rotating curling iron that creates curls at the press of a button.

It has a built-in timer that beeps when the curl is ready, which means you do not have to stand in front of the mirror trying to guess whether you have held the tong in place for long enough.

For anyone who has ever ended up with one perfectly curled section, one suspiciously straight section and a minor hand cramp after attempting to style their entire head, I can see the appeal.

The tool has a longer barrel designed specifically with longer and thicker hair in mind, with the 32mm option giving you more room to work through longer sections.

According to the brand, it is designed to create consistent curls from shoulder-length through to waist-length hair.

It also uses dual PTC heaters to speed up styling while distributing heat evenly across the barrel.

That could be especially useful on busy mornings when spending 30 minutes painstakingly curling every section of hair is simply not happening.

The automatic rotating function is another major drawcard. Rather than manually wrapping each section around the barrel, you place the hair into the tool and let the curling mechanism do the rotating for you.

One Amazon shopper with long hair said the tool made a noticeable difference to their routine, particularly because of the automatic rotation and longer barrel.

“I’m really loving this curling iron! It’s so quick and easy to use, especially compared to a regular curling tong,” they wrote, adding that the tool took roughly five seconds per strand and that the beep let them know when the curl was ready.

Another reviewer claimed they were able to curl their entire head in just six minutes, writing: “For years I have tried so many products to curl my hair and nothing is as easy as this.”

The TYMO CurlPro Plus also has a floating plate, anti-tangle technology and a 360-degree anti-scald design.

Its T-GLOSS tourmaline ceramic coating and negative-ion technology are designed to help create smoother, shinier-looking results.

The brand says curls can last for up to 72 hours, although, as with any heated styling tool, results will vary depending on hair type, styling technique and the products used.
