The BaByliss Rose Lustre, model number 2515DU, takes the number 8 slot in this guide and is the cheapest straightener in it at £23.97. It is a corded flat iron with ceramic plates, three digital heat settings between 180°C and 230°C, a claimed 30-second heat-up and a heat-ready indicator. That 230°C top setting is more heat than the two most expensive listings in the guide offer: the £186 ghd Platinum+ and the £111 ghd Original both stop at 185°C. Price and maximum temperature rarely move together in this market, and this listing is the clearest example of it.

The page is not entirely consistent with itself, though. One bullet sells "built-in multi-voltage functionality" for international travel, while the specification table lists the input voltage as 230 Volts (AC); a fixed-voltage tool and a multi-voltage travel tool are not the same thing, and this listing states both. Behind the 4.5 average, the rating breakdown shown on the page lists 73 five-star entries against 3 one-star. Everything below comes from the Amazon listing as it appears there — price, specifications and buyer comments included. We have not tested this straightener ourselves.

## Questions people ask

**How hot does the BaByliss Rose Lustre get?**

The listing gives a maximum temperature setting of 230°C, with three digital settings ranging from 180°C to 230°C.

**How quickly does it heat up?**

The bullet points claim a 30-second heat-up, with a heat-ready indicator to show when it is ready to use.

**Can I use it when travelling?**

The listing contradicts itself here: one bullet advertises built-in multi-voltage functionality for international travel, while the specification table lists the input voltage as 230 Volts (AC).

**Does it turn itself off?**

Yes. The listing describes an automatic 1-hour safety shut-off, and says a heat-proof mat is included for safe storage.

**Is it suitable for thick hair?**

The listing says the plates suit all hair types and that higher heat settings may be more effective on thicker or more textured hair. Buyers are split on this — one reviewer with thick hair says it does not straighten hers much, another says it glides through thick hair easily.

**How heavy is it?**

The specification table lists an item weight of 437 g, with dimensions of 35L x 3W centimetres.
