Currently I use this watch every day. I generally do 5k distance and it reacts exactly like it should. I prefer the buttons over the touchscreen like the Vivoactive line too. Generally I get about a week’s worth of charge, using it 3x for about 30mins with music for runs. Otherwise it’s a decent timepiece that does a handful of smartwatch functions. Holds ~700 songs and pairs quite well to my Jabra Elite Active 75t earbuds.
With that said, I purchased mine new from the mothership for $229 18 months ago and it is something like 3 generations old at this point. The 245 that came out after was a generation ahead (1/2 generation?) and the new 745 just came out. The 245 can be found for about this price, while the 745 is closer to $500 most places.
