Why it sits behind the Remington Keratin Protect Intelligent Straightener S8598

The Remington Keratin Protect Intelligent Straightener S8598 (9.0) beats the Diva Pro Styling Intelligent Digital Styler PRO211 Onyx (8.9) because it leaves owners a little happier.

About the Diva Pro Styling PRO211

The PRO211 Onyx is a corded flat iron with an LCD display and digital variable heat from 110°C to 235°C. The plates are ceramic and float, and the brand says they are infused with macadamia, argan oil and keratin. Diva Pro also lists Heat Boost 3 technology for recovering heat while you style.

Heat-up is quick, but the brand's page gives two sets of figures. The technical section says 30 seconds to 180°C, and the features section says 18 seconds. Treat it as under a minute to styling heat. The cord is 3m long, swivels and is heat-proof.

The brand describes it as multi-voltage, with a UK/EU plug adaptor, and says it switches off automatically after 60 minutes. One retailer listing for the related Wide model mentions 10 minutes, so that figure should not be applied here. In the box is the styler and an eco-felt storage bag that works as a heat mat. The Onyx comes in black, with Magenta and Violet versions of the same styler. The brand does not list plate width, weight or dimensions.

What owners report about the Diva Pro Styling PRO211

Owner feedback for this exact model is mostly short and positive, and it comes largely from one retailer's review pages. We found no forum threads or independent long-term reports.

Owners say it heats quickly and works well at lower temperatures than their old irons. They describe softer, shinier, less frizzy hair, and some say a straight finish lasts a few days even on a low setting. Several compare it favourably with ghd, and some mention a hairdresser recommending it. It is described as light and easy to hold, and as good value.

Complaints are few. Some owners wanted a travel case. One found no obvious off switch, and another needed some practice as a first-time user. We found nothing on how it holds up after many months.

Who the Diva Pro Styling PRO211 suits

Buy it if you want precise digital control, with low heat for fine or damaged hair and high heat for coarse hair, plus a long cord and a plug adaptor for trips abroad. The 3m cord also helps if your socket is far from the mirror.

Look elsewhere if you have long, thick hair, where standard plates need more passes: the ghd Chronos Max has wide plates. For an iron that adjusts heat by itself, the Remington Keratin Protect Intelligent Straightener S8598 is the better fit. The warranty is also shorter than on some rivals here, so check the terms before buying.

How we score it

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover hair straighteners for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 25 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in October 2026.
