I see lots of folks with Garmin's who like them and have had good experience with them, but in the last 18 months I have had to send back an 800, 810, and now the 820 within a few months of purchase, because they quit working

Initially, I had good experience from the unit

My experience with this product has been pure frustration

As a cycle computer, it gives you every you need but the connectivity issues mar that experience

Horrible experience with 820....

What a miserable experience

A terrible experience
