The only problem I have with the Astrale 8 is that the odometer is not programable. My batteries were running low (weak display) and I tried to change the battery as quickly as I can (took about 3 seconds from the time I popped out the old battery to the time I clicked in the new battery), but the entire thing resetted!

I was hoping that there would be a 10 - 20 second grace period where the computer would retain all the info. But guess what? My odometer read "0". Oh well. And I have no idea why this is one of the few Cateye computers that does NOT allow you to program your odometer. Almost all other Cateye computers have that function.
