This product is really helping me achieving better sport results Despite a few comments I've read in this reviews, the FLOOR, STEPS and other features are very accurate (haven't tried swimming yet).One important aspect is: ARE YOU AN iOS DEVICE OWNER? I am and I read a few people commenting that it FULLY integrated with Apple which is ABSOLUTELY not true.Think of the iOS integration as a READ ONLY integration, where you CANNOT do Write actions. For example: you CANT answer messages, you CANT reply to Whatsapp and other chats, you CANT reply emails you basically will use your Smartwatch as a READ ONLY mechanism where all your notifications from Iphone will also show up at the smartwatch screen.Although it was a bit disappointing to find this out, still the product matches my expectations. With a fairly good user of it, turning of several times for messages and Working out at least once a day, battery is lasting for about 48h. This could be an improvement: have a spare battery so that during the 2h-2h30m that it takes to charge you don't have to worry about it. (note: i choose not to charge when I sleep because I like the Sleep Tracking feature)So, bottom line, Great product I read A LOT of reviews in here and OTHER products and this has been the best cost-benefit.
