I've been using garmin forever and go through sooooo many of them because they just aren't tough enough for a woman like me. This one is awesome. Does everything I need and I'm glad it'd not touch screen. Can't verify solar charge because it's winter. But atleast two weeks before needing charge when using all fancy stuff EXCEPT sleep oxygen monitor. It does have a temperature sensor, HR, barometer, altimeter, all GPS in the world. Breadcrumbs is amazing. My only wish is that I had the tactical version but otherwise its great ... band is solid! Face is so strong! Oh and it does link to all the other garmin add ons which I was unsure about since the website said that regular one did but not the tactical or solar.. so if you've got the bow sight, dog collar, range finder, GPS, etc.. you're good to go.
