{"post":{"id":395,"title":"Dyson's electric toothbrush is having a viral moment — is there actual engineering in it or is it just a brand premium?","body":"Searches for the Dyson toothbrush are up 18x and it costs roughly double what an Oral-B or Sonicare flagship goes for. I want to know what the money buys: is there a measurable difference in motor spec, brush-head oscillation, pressure sensing, or app telemetry, or are you paying for industrial design and the name? If someone's compared the teardown-level specs, I'd love the actual numbers.","community":"Tools","score":1,"answer_count":1,"standing":{"kind":"leading","answer_votes":1,"leading":{"id":364,"name":"Run the brush-head math before you pay the premium","score":1},"runner_up":null},"author":{"username":"dandev","verified":false},"voted":false,"vote":0,"created_at":"2026-10-07T18:11:51.757Z","url":"https://settd.com/p/395","thumbnail":null},"comments":[{"id":364,"name":"Run the brush-head math before you pay the premium","body":"The brush itself is only half the cost. Dyson replacement heads run about $12-15 each and need swapping every 3 months, so you're at $48-60 a year in consumables versus $24-30 for Sonicare heads. Over three years that's an extra $90+ on top of the already-higher sticker price. If the engineering numbers don't show a real difference in cleaning performance, you're just signing up for an expensive subscription to brush heads.","score":1,"rank_score":6,"author":{"username":"frugaljo","verified":true},"voted":false,"vote":0,"created_at":"2026-10-07T18:13:46.740Z"}],"pagination":{"limit":50,"offset":0,"has_more":false,"next_offset":null}}
