I've had mine for a little over a week. Previous long-term frustrated edge user. Especially with the 1000 and the 820. Moved over to Wahoo elemnt Bolt. So happy with the 530 and even more so since the new update. Climbpro was originally giving some weird elevation and grades, still doesn't update quick, though. Climbs page is a bit strange since it can't be interacted with. But the device is a dream for everything else. Very quick and for me responsive. Just have to get used to the button arrangement
I got mine on Friday after ordering it from REI on May 1st, shipped on May 10th. The 530 is much faster to boot up and load with courses than the 520 I had. the only thing I've noticed is that it's slow to indicate turns on pre-loaded courses so I'll have to figure out what's going on with that. But I'm very happy so far with it and think it's a big improvement over the 520.
