Specifications
| Price (US) | Not published No current US MSRP could be confirmed: Wellue's own site states this model 'is currently only sold in the EU', and its old US product URLs now 404. Third-party US listings persist on Amazon/Walmart but no live price could be retrieved from those pages (JS-rendered listings blocked automated fetches). |

Source: getwellue.com (verified 2026-08-01) · corroborated by manuals.plus. Wellue's own current FS20F marketing page (fetched directly, now a legacy 'pages/' URL rather than an active 'products/' storefront listing) states the device 'is currently only sold in the EU', gives SpO2 range 70~99% with an 88% low-alert threshold, pulse rate 25-250 bpm, an OLED display with bar-graph pulse intensity, Bluetooth 4.0 to a free iOS/Android app, and 2×AAA batteries at 3.0V. The official user-guide PDF (Manuals+, mirroring Wellue's own documentation) instead states SpO2 range 70%-100% and PR 25-250 bpm and explicitly instructs 'Do not use the oximeter for more than 5 minutes without relocating the device to another finger', confirming this is a spot-check device rather than an overnight/continuous monitor (continuous_monitoring=false) despite Bluetooth app-trending. An in-app screenshot embedded in that same user guide shows a live 'Pi: 10.9%' Perfusion Index reading alongside SpO2 and PR, so perfusion_index=true. No SpO2 accuracy percentage (ARMS) or battery-life-in-hours figure is stated in either source, so both are left null. No release year found. No priceUsd is assigned since the brand's own current page disclaims US sale and no live US retail price could be independently confirmed.
