Just about perfect... almost
If Wahoo can work on making this a lower profile dongle, say half its current size, it would be much more versatile to use! It's hard to get into some standard cases with such an obtrusive dongle. Otherwise, it does exactly what its advertised to do and does it well. Hoping for a slimmer profiled rev 2!
Needs a modification
Im currently using a Wahoo heart rate sensor and bike speed/cadence sensor with my Iphone. They work very well with Imapmyfitness and are a very convinient package , BUT.... I would like to seriously recommend a modification to the manufacturer to add a small eyelit to this device so a string, lanyard, or keychain could be attached as it is very small and easy to lose
Agree on modification to add eyelit for keychain
I love the Wahoo Key. I no longer use my Garmin ANT+ USB to upload to my laptop, I use the Wahoo Key to do that. I have the same issue where it is hard to find sometimes. I little keychain eyelet of some sort would make this pretty awesome.
