For the price of this watch I am really impressed because I have bought a higher priced smartphone before and it wasn't even touch screen. This works really well. Just remember for this price you are getting a bargain because all you need now is a SIM card. You will also need a TF card for taking photos. It has a sleep mode so it can keep up with your sleep pattern. It has step counting which is great for when you're trying to get so many steps in a day. The camera actually takes good photos being on a watch. I was also impressed with the calling feature it picks up quite well and you can talk to someone through your watch. How amazing is that feature. I really liked that.
