🧠 Smart Buying Tips (Tech Ring / Smart Ring Edition)

• Match ecosystem & compatibility: a ring is only as useful as its app and OS integration (iOS, Android, Samsung Health, etc.).

• Check subscription model: some rings require paid subscription to unlock full insights or trend data.

• Prioritize sensor accuracy & validation: biometric tracking is only meaningful if it's reliable.

• Comfort & wearability matter: if it’s uncomfortable, chances are you won’t wear it consistently.

• Data privacy & ownership: check how your biometric data is stored / whether you own it.

  
  

⚠️ Important Notes / Disclaimers

• These rings are sophisticated health / biometric wearables; they are not medical devices (except in specific areas like ECG where claimed).

• Pricing and availability are subject to change; always verify before purchasing.

• Newer rings (e.g. Circular Ring 2) bring innovation but less long-term track records.

• Some smart ring brands have faced issues such as battery reliability or firmware bugs — worth reviewing long-term user reviews.
