Cost, Quality, and fast shipping to the U.S. (ordered on a Thursday and received the following Tuesday (today 7/9/2013). I purchased 5 of these watches and am going to purchase 4 more today! I also purchased some very stylish sunglasses that look like my Ray Bans (also very skeptical) and they look great! Not to mention they are ~$6!!
Needless to say I will be ordering more product from this site. Am very pleasantly surprised.
