ok. i finally received my Apple Watch 42mm SG BSB on Tuesday. its a decent looking watch with decent functionality but im already encountered with several problems. so posting here so that new buyers can take it as grain of salts. 1. iPhone's Apple Pay Credit cards and Apple Watch's Apple Pay CC are used differently. When you sync your watch to your iphone, you expect it to get all the CC stored in my passbook to transfer. nope. you have to authorize them again. it doesnt consume too much time but i kinda bogged my head when i saw them. Plus i am very concerned about the security of storing CC on my Apple Watch. i mean with the iphone, atleast it needs your fingerprint to verify the card owner whenever you pay. With the stolen Apple Watch, you dont. yes you can setup passcode that automatically locks up when you took the watch off but still, fingerprint is alot more secured than just putting 4 digits passcode. 2. Charging speed is super slow. Well, you cant really expect too much from tiny device like this watch and its magnetic charger. My watch went down to 40% after work so i decided to charge them before i go out for house party. Plugged it into 45watt 5 ports Anker charger which charges my iPad Air 2 with full speeds. After 1.5 hours, it was 65%. Seriously?? So you'll need 6 hours to fully charge from 0 to 100?? i can already see myself putting my watch on charger at work because i forgot to charge it overnight. and its gonna take forever. 3. some portable external battery bank wont work. i own Anker Astro E5 16000mah External Battery(http://amzn.com/B00N2T7U90) which has functionality of auto-turnoff when it does not detect any device connected to the USB port. auto-turnoff is a must since it prevents batteries to drain out by itself and dies. But this magnet charger, does not sync any data or output connectivity through USB. Which makes the batteries to turnoff by itself. I tried couple of my friends' external batteries from variety brands but no luck. Some companies are making exclusive portable charger for Apple Watch but it really sucks that you have to carry another battery bank when Anker ones can charge iPad, iPhone, and my bluetooth headphones just fine. ok im done with rants. To be honest, its a beautiful piece of gadget. And it has great potential to do more things. But just like every online reviewers said. its first gen. and you can easily spot many problems software-side and hardware-side. i can already see myself stressing out to take them off and on to charge it frequently. i would try to avoid buying one unless you have spare money to throw. or just buy two of them so you can switch it around..
