Our verdict
The Series 3 stickers at $149, but the receipt above is the real price: $635 over three years, or about $14 a month in running costs after the box arrives. The subscription is not optional: without a plan ($8–$19/mo) the core function simply doesn't work, so treat the hardware price as a down payment.
There are no meaningful consumables to budget for. Be aware the core function depends on the app and cloud staying up; an outage at their end is an outage at yours.
