Bests & Worsts Reviews from Amazon

My original Charge 2HR quit counting stairs after a few months. After a lengthy phone conversation with a very nice Fitbit person, it was determined to be defective and a new one was sent. Fine, EXCEPT this supposedly new one counts every move of your wrist as a step. I have gotten over 40 miles a day! I have only had it for a couple of weeks, but have won badge after badge! So after another lengthy phone call with another nice person, this one too has been determined to be defective. Got no conclusive answer regarding if a truly new one is being sent or if I will be inheriting someone else's problem in a poorly refurbished model. She said "We consider them new.' Not sure what "consider" might mean. As much as I like wearing my Fitbit Charge HR, this has been a real pain.
