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.

Everything i need
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

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.

Great Value, Durable, Easy to Use,
I purchased this watch to train for CG Games and it has exceeded expectations and has greatly assisted me with pacing while not being too big on my wrist. A great value!
