Clamp or wand, and one diameter
The family divides on one mechanical question — clamp or no clamp — and then on a single number, the barrel diameter. A clamp holds the end of the section for you and leaves a small crease where it grips; a wand needs a heat-resistant glove and leaves none. A tapered barrel produces curls that tighten toward the tip, a straight barrel produces an even spiral. Automatic curlers form the section inside a chamber on a timer, which is a third mechanism again. Temperature ranges are reported as published, alongside coating, heat-up time and whether a glove is in the box.

A 25 mm clamp iron is enough for classic curls. The lowest recorded price on the shelf; today's price sits beside it.
The published heat-up time says how long you wait before the first section. Not every iron publishes one.
Interchangeable heads in different sizes give several curl shapes from a single handle.
A battery curler does without an outlet; the stated runtime decides how long a session lasts.
Let the curl cool coiled in your hand or pinned before releasing it. It is cooling that sets the shape, not heat.
Small diameter for tight curls, large for soft waves. The diameter decides the shape more than technique.
Many recommend it for regular use, applied to dry hair before curling. The sprays in the heat protection category state a protection temperature, or do not.
A few seconds, at the temperature the manual gives. Longer does not improve hold; automatic curlers set that time with a timer.
With a clampless conical wand, yes: you hold the tip of the section by hand near the hot barrel.
Alternating direction from one section to the next gives a more natural result. All curls in the same direction look very uniform.
Cold and unplugged, with a soft cloth. Hairspray residues burn on and catch the next section.
Never with a hot iron, except on an appliance specifically designed for it. The water vaporizes inside the fiber.
Four of the twelve do, and all four are European references: the BaByliss C325E, the Grundig HS 6230 and the two Remingtons. The eight others publish no temperature at all, which is why both picks above name a European tool.
Because the four tools that publish a temperature are European references and their makers publish Celsius. We lead with Fahrenheit and keep the maker's own figure behind it; the conversion is exact on every value here, so nothing is rounded into existence.
It is cooling that sets the curl, not heat: let it cool coiled before releasing it. The diameter decides the shape, alternating direction gives a natural look — and a clampless conical wand makes a glove compulsory.
There is no table here, and the reason is in the listings. The figure published most often across these 8 products is barrel, given by 4 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.
