Coanda at two prices
The engineering, or the second tool?
Two air stylers built on the same aerodynamic principle, far apart in price. Dyson documents the mechanism in unusual detail; Shark makes the same body work as a full hair dryer.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Take the Dyson Origin if you want the mechanism documented and the controls separate. It is the only tool on this site that publishes the motor speed and the air pressure behind its own marketing term, and three airflow speeds independent of three temperatures is real control.
Take the Shark if it has to replace a dryer as well. Six attachments including a concentrator and a diffuser, a published weight, and a case. What you give up is every figure about how it works.
An aerodynamic phenomenon where a jet of air follows a nearby curved surface, taking the hair with it and wrapping it round the barrel. Both makers name it; only Dyson publishes the air pressure it says is needed to produce it.
No. Both give a number of settings and no figures, and the i.d. gives neither. Three of the nine air stylers on this site do publish degrees, and the hottest figure among them is 230 °F — where the straighteners here run to 446, 450 and 455 °F. The comparison is available; it is just not available on these two.
V9 motor, 110,000 rpm, 3.2 kPa · heat measured 40×/s · 3 attachments
The entry Airwrap: the Coanda effect driven by Dyson's V9 digital motor at 110,000 rpm and 3.2 kPa, with airflow temperature measured more than forty times a second, three intelligent attachments, three speeds and three temperatures.
Best for: The Coanda format from the company that engineered it, with the motor figures published.
Dryer and styler in one · 6 attachments · heat measured 1,000×/s · 700 g (24.7 oz)
A tool that converts between a hair dryer and an air styler, with two auto-wrap curling barrels, a paddle brush, an oval brush, a concentrator and a diffuser, measuring its own heat a thousand times a second. Case included, 700 grams.
Best for: One tool instead of a dryer and a styler, in a bathroom with nowhere to put both.
