Been using it for 6 months, including 15 hours 45 minutes on the dirty kanza this year. Overall I've been pleased. Like you, I don't need live mapping, etc., I just want something to pair to a speed/cad sensor and HR monitor and record my ride. Auto-upload to Strava was a little finicky at first but seems to be fairly smooth now.


I've had one issue that has happened on 3-4 rides (over 6 months) -- the distance display will suddenly add an insane amount of miles to my ride -- jump from like 35 to 105 or something like that.


Luckily, once the ride syncs with Strava, it gets auto-corrected because Strava uses the actual GPS data for its numbers.


I've emailed support, they confirm it is a hardware issue and they're working on a firmware update. Their advice is to stop using the Wahoo speed/cadence and HR sensors. I'm not sure if this is specific to Wahoo or all sensors. Anyway, that's stupid and I'm not going to do it. The whole point is to have HR and cadence data during the ride.


Also, they haven't updated the firmware since December, so I don't know how much continued support this product is getting.


The big reason I chose this instead of the Garmin 20/25 is because of the battery life. I've never gone all the way to 22 hours but it has certainly lasted as long as I've needed it to, even on the DK. I still enjoy the unit, but I'm getting a little disappointed in the lack of support for this fairly significant bug.




edited to add:
I also tried the Wahoo first -- it doesn't play well with Android and I found it to be slow and laggy. I returned it.
Another big positive for the Lezyne - satellite acquisition is super fast. I turn the unit on in my basement and it still manages to pick up signals within 30 seconds or less.
