No issues with my Fit 2 for 2+ years--- until recently-- heart rate monitor contact points have started to "burn" me causing a painful and itchy rash like irritation under the face of my otherwise completely functional watch. There are 2 distinct bumps on my wrist at the origin of this "rash" that line up directly with the contact points underneath so this is definitely the culprit. Watch works wonderfully aside from that so it is very frustrating to now have to replace a pricey gadget due to something that should be a minor issue that should last a lot longer than this.
