Not worth $700 vs a $50 dryer…
My hair dries fast. It looks good. But I genuinely cannot tell the difference from my old $60 Conair in terms of daily results. This is a luxury product and the premium is about feel, not function.
Source: RedditThe Dyson Supersonic HD15 hair dryer features a V9 digital motor spinning at 110,000 RPM housed in the handle for better balance, plus a thermistor that measures air temperature 40 times per second to protect against heat damage.

| Weight | 690g — motor in handle shifts balance point |
"My hair feels so much healthier after switching. Six months in and I can see real improvement in texture and shine. The lower heat damage is not a marketing claim."

"The flyaway smoother attachment is worth the upgrade alone. My blowout looks finished in a way it never did with my old dryer and round brush."

"The handle balance is the thing nobody talks about. My wrist used to ache after drying my long hair. No problem with this."

"Third Dyson dryer in 12 years. Each one lasted about 4 years of daily use. At the price it needs to — and each one has."

Source: RedditThe heat-sensing slows drying on thick hair…
The temperature control is great but for my very thick hair it throttles back before my hair is fully dry. I end up using it longer than I expected.
Source: Amazon reviewerReplacement attachments are expensive…
My concentrator nozzle cracked and a replacement from Dyson was $45. At this price point I expected the accessories to be more durable.

The magnetic attachment is convenient but the styling concentrator pops off if I angle the dryer downward too sharply. The other attachments stay on fine.
Source: Amazon reviewerThe Dyson Supersonic HD15 is the best hair dryer for anyone serious about long-term hair health — its precision heat control demonstrably reduces temperature damage compared to conventional dryers, and the handle-balanced motor makes extended styling sessions more comfortable. For daily users with fine, color-treated, or heat-damaged hair, it's a worthwhile investment. For occasional users or anyone without a specific concern about heat precision, the Conair InfinitiPRO at $49 CAD delivers 80% of the drying performance at 7% of the price.
