The first watch/charger wouldn't charge. Contacted customer svc to try to get a replacement charger and they couldn't send just the charger. They sent me a whole watch package and told me to keep the first one. I didn't think it was an issue with the watch. I was sure it was the charger and, I was right. Second watch came in, I plugged in the new charger, plopped the old watch on the charger and it charged straight away. The new watch also charged right away on the new charger.I have to say, aside from wonderful customer service, this watch took me about an hour to figure out. I have purchased and returned sports watches because I was unable to figure them out for DAYS, even with instructions due to program/phone compatibility problems. This has been the easiest watch to set up out of all of them.The ECG program is not currently functional, which was one feature I was interested in, but this watch has a stress indicator, and a hydration sensor, which I need both. It has lots of bells an whistles, too many to mention, but the bottom line is, YES! I would buy this watch again.The only problem is the battery life.I decided to reduce the battery usage at night by disabling some appAbsolutely perfect condition! I was a little worried about buying refurbished, but it looks brand new. Glad I bought this one rather than spending 250 for "new". I was afraid it would feel big and clunky, since I'm used to smaller watches, but its very light and comfortable. I did buy different bands for it because I don't like the wide straps. Super easy to change them out. Very happy with this purchase.Got this refurbished. Works great so far. My boyfriend got a brand new one. I wear it everyday. I've never really usually wear a watch before, so I thought I wouldn't like but I do so far!I bought this watch as a renewed product. Looks and works brand new. Came in original box. I would recommend paying 50% less for the renewed item. Comes with guaranteeThis watch looked brand new. It was also in its original packaging. No complaints here even came a day earlyThis watch was a renewed one but the battery only stayed charged maybe 4 hours max with very little use. I would not recommend this one.Battery didn't hold a charge been 4 days soon to be 5 still haven't received my money back ? they will do ANYTHING not to give u ur money and they r a 3rd party seller heads up
