Cycling computers

Since it seems we have a few other cyclists on here, I thought I would ask for a recommendation. I'm looking at bike computers, and I've been going back and forth between Wahoo and Garmin. I don't need anything super fancy, so I've been looking at the Bolt or the 530. I really want it for making a route on the computer, and then getting directions at turns (along with the basics like speed, distance, time, etc.).

My biggest priority is stability and battery life. I've read some reviews of the Wahoo saying it crashed or froze on them, which would be a huge turn off to me. My current "computer" is just a simple magnet on the wheel that runs a sensor - it never crashes or freezes or anything like that, and I change the battery about once or twice a year.

So, I'm curious if anyone has suggestions or experience with these.

And also I just wanted to get more cycling content on here... :-)
