Yep, I have given up on mine. I noticed it shorted me on a ride last week. I knew I had gone at lest 1.6 miles. Ionic said 0.68 miles. So on the way back, I turned on Endomondo on my phone. It said 1.77 miles. That was my final straw. I will still use it for my steps and music but not the GPS & Exercise. Deeply regretting this purchase. It's really sad if Fitbit screwed this up with an update. And they obviously don't care. They probably are hoping everyone will buy another one. Not me. Never again.
