The Revlon One-Step Style Booster RVDR5292UKE takes third place in our guide to hot air brushes. It is a round brush dryer with a 38 mm ceramic-coated barrel, three speeds and a 2.5 metre cord, listed at £29.99 with 4.4 out of 5 from 4,246 ratings. The rating distribution supports that average rather than fighting it: 70 per cent of the ratings are five-star and six are one-star, which works out at roughly 4.4. On a page where numbers rarely agree, that one does.

The spec table is where it gets awkward. The voltage row reads 120 Volts, on a listing priced in pounds for UK shoppers, and nothing in the listing describes the tool as dual voltage or switchable. The wattage row says 820 watts, which is well below the 1,100W and 1,200W blow-dry brushes that also made this guide, so this is a lower-power tool than the "salon blow-dries" opening line implies. Two further fields are effectively blank: Hair Type is answered with the single word "Dry", and Recommended Uses For Product with "Drying", on a tool the copy says also curls, flips and adds root volume. The warranty field reads only "1", which gives you neither the unit nor the period. Everything here is taken from the Amazon listing as written, not from a test of our own.
