I really liked this....when it worked, which has been less than two out of the three months I've had it. I guess if I think about it, my primary beef is with Samsung due to their truly terrible handling of the issue. The first one I got wouldn't connect to my phone so they told me to take it to the Samsung Experience at Best Buy and their employees there would get it running. The employees couldn't and advised me to send it back for an exchange. I did and when the replacement wouldn't work either, I returned to Best Buy at the urging of Samsung support. They again had no clue and admitted that they knew a lot less about the tech than Samsung thought they did. Luckily, a Geek Squad member heard our conversation and stepped in. He owned a different model and knew a trick that finally got me connected. For the most part, I was pleased with the watch and its performance for the next seven weeks until one day, the watch started vibrating and wouldn't stop. I had to kill it by holding down the button on the side. After that, the phone would take three hours to charge and the charge would last an average of five hours, far less than the 18+ it had averaged prior to the uncontrolled vibration. After contacting Samsung and explaining in depth the problem, they had me send it to them for repairs. I was very frustrated with the watch at this point. They offered to expedite the repair and have it back to me in just over a week. The day before it was to be returned, I got a call from them asking me to explain to them again what the issue was because they had tested it and everything was working. I explained again and then waited. Every person there asked me to explain again in depth what my issue was during every call and said that they were taking notes but whenever I had to call in again, it was as if there had never been any notes taken at all. This was extra frustrating because I had my calls dropped and was transfered off into oblivion multiple times.About four days after it was supposed to have come back I emailed them asking what was going on. the next day I received an email early in the morning saying that they had found nothing wrong with it and it was being returned. I was livid. Then, I received another email saying that they had found the problem and fixed it. I called them and the person in the repair dept was overtly rude to me and told me that nothing could be done until I received the watch back and checked to see if it was working properly. He absolutely refused to do anything until that point. In the mean time, I had been without the watch for two weeks. When it arrived the next week, a whole week past the day they had promised it to me, it was still not working.At this point I contacted them and insisted that they just replace it and stop wasting my time. They absolutely refused and one rep lied to me outright about it. They gave no option other than to send it to them again. The only concession they offered for the massive inconvenience was overnight shipping to get it to them more quickly. I dropped it off on a Tuesday and on Saturday, finally received notice that they had received it. Overnight shipping is pointless if they're going to take three or four days to process it in for repairs. It has now been nearly two weeks....again and I do not have the watch back. I received another email saying that a part they needed was on indefinite back order and they would let me know when it arrived and was shipped. I was pretty mad so I called them. The guy on the phone said that the part had arrived and they were shipping it out that day. He didn't seem to be aware of the overnight shipping promise. I again stated that they should send me a new watch and at this point they should upgrade me to compensate for their ridiculous incompetence and horrible customer service. The rep didn't even respond to that.Samsung has lost my family as customers at this point. This has been a truly bad experience and even if some of their products are cool, it's not worth having to go through this misery if something goes wrong. I'm not just saying to not buy this watch, I'm saying to not buy Samsung at all. LG, Motorolla, HTC, Panasonic, there are so many other good OEMs out there with good products. Don't spend your money with a company that takes their customers for granted this badly!
