Bests & Worsts Reviews from Amazon

I bought a 40 mm.. Took off charger at 6:30 am at 100%. When I got home at 4:30 pm it was at less than 50%. Drove me crazy. So I splurged and bought 44 mm for $30 more. OMG. I wear all day, same time as 40 mm, and it's at 80%. Don't skimp. Buy the 44 mm, and save yourself almost $400. There are more bands available for 44 mm. Battery life is SO much better. Options are the same (faces, apps, etc.), but 44 mm is hands down the winner. Awesome!
