BaByliss ST393E review

Six temperature settings from 140 to 235 °C (284 to 455 °F) on titanium-ceramic plates, thirty seconds to heat, an anti-frizz ionic function, a heat protection mat in the box and a stated five-year warranty.

Where it leaves us The widest temperature range and a mat in the box — and no price on amazon.com to read them against.

Six temperature settings from 140 to 235 °C (284 to 455 °F) — 284 to 455 °F, the highest ceiling published in this group — on titanium-ceramic plates BaByliss calls Advanced Ceramics. Thirty seconds to heat, an anti-frizz ionic function, and a reinforced housing the company puts forward for durability.

A heat protection mat is supplied. That is the accessory that separates a straightener you can put down from one you cannot, and it is not standard.

Two gaps. The plate width is not published, which is the specification most worth knowing on a straightener. And there is no live offer on amazon.com at the time of writing: nine of the twelve straighteners here publish a price, and this is one of the three that do not.

Set against the shelf, the picture is mixed. Four hundred and fifty-five degrees is the top figure among the twelve straighteners here, just above the 450 °F that the Arkam and the American Remington reach. But six settings is among the fewest: the Arkam gives twelve, from a floor of 250 °F, which is both a lower starting point and twice the choice — at $29. The Remington S3500 gives ten. So the argument for this iron is the ceiling and the supplied mat rather than the granularity, and the figure that would settle it is the one this page cannot print.

The good points, and the rest

Strengths

  • A heat mat is in the box, which is the accessory a hot straightener genuinely needs
  • Five years of warranty, the longest stated in this group
  • A reinforced housing, which BaByliss puts forward as a durability specification rather than a coating claim

Compromises

  • Six settings across a 95-degree range is a coarser step than the Remingtons' nine and ten
  • Thirty seconds to heat, twice the Remingtons here
  • Plate width is not published

What people ask about this

Why does a 140 °C (284 °F) setting matter?

Because the two Remingtons in this group start at 150 °C (302 °F), and a straightener cannot go below its lowest setting. Whether 140 °C (284 °F) is the right setting for any given head of hair is not a question this page answers — BaByliss itself advises a lower temperature for fine, bleached or colored hair in its own listing, and the manual is the authority.

What is a heat mat for?

Putting the tool down on it while it is hot, and rolling it up to store while it is still warm. It is a cheap part that most straighteners leave out, and its absence is the reason a great many worktops have a mark on them.

Our score

7.8/ 10

The widest temperature range and a mat in the box — and no price on amazon.com to read them against.
