# Fi Series 3+: specs and price

**Price (US):** Not published (No standalone device-hardware MSRP (excluding subscription) is published for the Series 3+. Fi bundles the collar with a required paid membership: technobark.com (Feb 24, 2026) states "you actually pay for the subscription and the collar comes with it," plus a one-time $20 activation fee. Retailer/review pricing reflects subscription bundles (pawtechreview.com lists $189.00, matching Fi's 1-year prepaid membership; the technobark title references a legacy "$149"), not a device-only price — so priceUsd is null.), as of 2026-07-13.
