Used Suunto 9. Please check the following and purchase with your understanding. Used for running and trail running for about 4 years. The battery condition is poor, and it only lasts for about 2-3 hours during measurement. Other operations were fine until just before use. Connection with the app is also fine. The original band broke, so I purchased a replacement from Amazon. The original charging cable is also included. The screen has a film on it, so there are no direct scratches or stains. As mentioned above, the battery condition is poor, so it is recommended for those who want to use it after battery replacement, for parts, or for those who want to try a Suunto for now.
