Dusted it off this week for the bimonthly chance at redemption because I just got a L508 radar (which I'm still unsure about too). I've done 4 rides, all between 1 and 2 hours:
-Might be just luck, but I found the android app to be much less buggy. Paired fast, synced fast, no timeouts. Just an issue syncing to strava but they're not really to blame because strava handles email changes very poorly. Still a nice surprise, the app works.
-Their "climbpro" is a joke. It first needed to be activated somewhere deep in the app. I imported a route from their inapp route planner, which is no komoot but it works on par with the builtin garmin/igpsport/wahoo route planners. I got climb alerts for ghost climbs that didn't exist eg. 400m@7% when the road was fairly flat 1-2% up or down, some climbs were mysteriously split in 2, eg. 0-30% of a consistent 6% climb, then later the last half of it when there was no flat section, climbs that started way too late when I was well into it, and some climbs that kept going when I was actually done climbing.
The "average grade remaining" is also pathetic. It will correctly identify 4km remaining and 250m remaining, but the calculation will be way off and fluctuating. It should be third grader math but it might say 3%, 14%, 6% etc. RNG. How can they fuck this up?
-With four connected sensors, auto brightness (fairly sunny week) and a route loaded, it drains ~8% per hour, but I had one 1h20 ride go from 58 to 19%! In similar conditions, my IGS630 drains 3 or 4% per hour max, despite being older and used a lot more often.
-I still think the hardware is flawless. It's crazy responsive, very readable. It's just the software that sucks.
If ALL you need to do is stare at data fields and the occasional turn by turn, it's great, but for the money I expect a lot more. I hope the next IGPSport binavi will be good
