Question about Samsung Galaxy Watch

I've had it for a few days and I'm delighted with it. It offers a multitude of sports programs, and automatically detects when you are walking, running, swimming (not all sports but 4 or 5 I think). It's also pretty! And the battery lasts about 2 days and a half (without the "always-on display" otherwise it is reduced to 1 day, 1 day and a half). Honestly, go for it with your eyes closed!
