I picked my 42mm Space Gray Apple Watch Sport up from UPS Monday morning. I've been using for 3 days, and have had no problems. It works exactly as expected/advertised. It's a lot smaller than I expected, but in a good way. It's beautifully designed, and very light. The screen is bright and gorgeous. I'm very happy I went with the Sport aesthetically and budget wise. It's remarkable for a first gen product, truly. Everyone asks me about it, and asks to see it. Most people with low expectations are impressed once they finally see it, that it's "much better than they were expecting" Minus the cashier at Walgreens yesterday, hoping I didn't get robbed... It tells the time wonderfully. These watch faces are just great. I've taken a fancy to the Modular, I hope there are more options for feature rich faces in the future. Battery life is great / It charges from dead to full in ~2 hours. Used it extensively yesterday, taking it off the charger at 7am and still had 20% gas in the tank at midnight last night. Been off the charger now 13 hours today, and I just dropped to 50%. All notifications seem to be working. I've received all notifications I'm supposed to be receiving. No issues or errors there. All taptic feedback is working. Taps me when it's supposed to, I haven't missed very many. I do have it on the heaviest non-prominent setting. Heart rate monitor is working. Had no issues, worked great on my jog today! "Hey Siri" on wrist raise works great. Had no problems with getting her to do my bidding when raising my wrist. No Wrist detection problems I do have a wrist tattoo, but it's on the inside away from the watch face. If you were supposed to wear the watch on the inside, I might be in trouble... but, I've had no problems with wrist detection not working / having to type in a passcode 100 times. Activate on wrist raise is working just fine. The only time it doesn't, is if I have my hands over my head and bring it down (relaxing on the couch) or something. But even then --- you just tap the screen and it poofs on. Cover it up with your palm to turn it off. No black sport band problems. The black sport band is durable and soft. Holds steady, and no "peeling" or otherwise. It's not annoying & enables me to keep my phone out of reach. I love it. It's liberating and freeing. I know there's nothing important happening. It stops me from going down the rabbit hole that is my phone --- so often I get a notification that's not really important, and the next thing I know I'm playing Clash of Clans instead of working. With the super quick interaction time, it helps curb that. The only thing I haven't tested it with is a third party bluetooth device, so I cannot speak to that yet. Everyone just seems to have some sort of issue, or problem. So often, we only see the negative, and try to turn it into the next "-gate" I just wanted to report that mine works wonderfully, as expected... and I'm very pleased with it. Haters gonna hate.
