    It’s a good tracker just a little simpler than I would have hoped for the long awaited gen 4. It’s a better all around design but should have upgrade options for gen 3 holders. One gripe I have is the battery life is not 8 days. I have to charge it twice in 8 days so it’s kinda a let down. My gen 3 had better battery life and it’s 2 years older.

    This ring was amazing. As someone who has terrible sleep it helped me identify patterns that seem to be poorly effecting my sleep and health. Im still working on it but the ring has definitely been an important tool.

    Its a very interesting ring and it has several features. It is similar to a fitbit but i think more accurate. Its nice to have the oxygen level, glucose level, and the advisor to suggest things.
