Nice for the price

I bought this some time ago. It is a good GPS watch for the price. I do a lot of walking and like to focus on speed and distance. Does it very well. Notifications are good as well.

Light weight, easy to read and understand.

I did my first run/walk today and figured out how to use and believe me that is a accomplishment, still need some help with it but I will get that next week with a grandson.

Great for running

I replaced my Fitbit Charge 2 with a Fitbit Charge 4 because it had GPS. The Charge4 would take forever to connect to GPS and continuously disconnected in the middle of runs. Their customer service could not fix so I exchanged it for this Garmin. Garmin connects to GPS quickly and the large display makes it easy to read stats while running. So far, I’m very happy with the Garmin.

I bought this a few weeks ago and it has been great, it tells me everything i need to know, the only thing that bothers me is the size of the screen but besides that it’s fine
