It's all a bit hit and miss for me. I did a run last night with no dropouts at all but prior to that almost all of my runs have suffered badly with multiple disconnects and gaps in my connect data. Most are quite short but there are also a number of them lasting 15 seconds+. It's such a great bit of kit that I don't want to get rid of it and I'm going to try it later without the power metrics as a regular footpod. The GPS/instant pace performance on my F5 is so poor and I'm hoping that the Stryd unit will remain connected and give me accurate feedback for both pace and distance.
