  • Great Watch Except a Little Dim in Low Light

    I had an Apple watch 4 for 5 years. I finally upgraded to the 9. The only complaint I have is it sometimes dims too soon and you can't adjust the dimmer sensor as it can be a little difficult to see in low light. You can adjust the brightness, but it dims on its own to maintain battery life. Other than that it works great and I like the additional functions.

    Good. I didn’t want the sport loop but the other one wasn’t great as well. It was velcro. I replaced it with a third party strap right away. You have to buy a protector and case right away.
