Things to Consider

• Make sure your device supports the Lenovo Digital Pen 2 — it's intended for specific Lenovo 2‑in‑1 or touch laptop devices using the correct digitizer protocol. Some users report compatibility issues when used with unsupported screens. :contentReference[oaicite:14]{index=14}
• While the spec says “up to 4,096 levels”, actual performance depends on the device’s digitizer hardware and drivers—some users note the experience is less smooth than they hoped. :contentReference[oaicite:15]{index=15}
• The pen uses a non‑rechargeable standard battery (AAAA) rather than built‑in rechargeable; if you prefer rechargeables you might look at other stylus models. :contentReference[oaicite:16]{index=16}
