Fi Series 3
What the marketing price hides
The Series 3 is marketed at $149, which is 23% of what you'll actually spend over three years. The rest is the mandatory plan: at $8–$19/mo, the subscription adds $486 (midpoint) over 36 months — more than the hardware itself. The sticker is a down payment. Note: membership required for GPS tracking.
One more cost that isn't on the receipt: dependency. The core function needs the app and the vendor's cloud — if either goes away, so does the product you paid for. See the full Series 3 verdict for the score breakdown, or compare it inside its category on the device database.
