Plate width, plate coating, and a stated temperature
Three figures separate straighteners, when the maker publishes them. Plates: their width decides how much hair passes per stroke, but the European straighteners here do not publish it — the Remingtons give the length, 110 mm (4.33 in). Plate coating — ceramic, tourmaline, titanium — decides how the plates glide and how evenly they hold heat. Temperature is the third, and here we report and do not advise: manufacturers publish a range, commonly up to 230 °C (446 °F), and the setting appropriate to any given head of hair is a question for the manual and for a hairdresser, not for a review site. We also compare heat-up time, whether the plates float, and whether auto shut-off is fitted.
110 mm (4.33 in) plates · 10 settings, 150–230 °C (302 to 446 °F) · 15 s heat-up · auto shut-off
Floating plates 110 mm (4.33 in) long, with a ceramic-tourmaline coating, ten temperature settings between 150 and 230 °C (446 °F), fifteen seconds to heat, and an automatic shut-off after sixty minutes.
Best for: Short to mid-length hair, and a first straightener where the temperature must still be adjustable.
110 mm (4.33 in) plates · LCD, 9 settings 150–230 °C (302 to 446 °F) · Pro+ 185 °C (365 °F) · 15 s
The same 110 mm (4.33 in) floating plates on a digital body: an LCD display with nine settings from 150 to 230 °C (302 to 446 °F), a dedicated Pro+ setting at 185 °C (365 °F), a temperature boost, and a keratin and almond oil ceramic coating.
Best for: Someone who wants to set an exact temperature and see it, rather than trust a dial.

The published heat-up time says how long you wait before the first section. It says nothing about the quality of the finish.
An adjustable temperature range and floating plates already exist at the bottom of the shelf.
The lowest that straightens in a single pass. Going over three times at a low temperature damages as much as one pass that is too hot.
It is professionals' general recommendation for regular use. It is applied to dry hair before straightening.
Never, except on an appliance explicitly designed for it. The water turns to steam inside the fiber and damages it.
By moving without stopping, in one continuous motion from root to tip. A pause mid-section leaves a sharp crease.
Appliance cold and unplugged, with a soft, slightly damp cloth. Styling-product residues burn on and catch.
With rounded plates, yes, by turning the iron around the section. Plates with sharp edges leave a crease instead of curling.
Ceramic heats evenly, titanium comes up faster and higher. Titanium is more for very thick hair.
It is repeated heat exposure: spacing it out and alternating with natural drying is what professionals recommend.
The right temperature is the lowest that straightens in one pass: three gentle passes damage as much as one that is too hot. Never on damp hair, never a pause mid-section — that is what leaves a crease — and clean the plates cold.
There is no table here, and the reason is in the listings. The figure published most often across these 12 products is price, given by 8 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
