Are they good? I really want one but I have a moto Z phone and I'm not sure which one to get! I really wanna use it for when I exercise to keep up with how much I'm doing and my heart rate! It would be helpful if I could use it like an apple watch and check messages/phone calls also.

Any suggestions???

***I got one but all it shows is "Garmin" and it won't turn on or anything I thought it might be because its dead since it just came in but it wasn't idk what I'm doing wrong please help!***
