Glad to hear you like it so much! I just got mine in the mail and am excited to get riding with it. I wanted something simple that could keep track of my distance, cadence and heart rate without having to have my phone in front of me. I was torn between this and the 320, as I wasn't sure if I needed the mapping, but it was only $30 more, so I figured why not? All of the reviews I've seen have been positive, and hearing that you've used this for a year and are happy with it makes me feel good about my purchase.
I bought this when I thought Ihad broken my Bryton Rider 10. I am a fan of the Bryton devices, never let me down(unless I forget to charge it) This has some new features. A fourth button makes navigation easier, but I wish the rides would auto save. The rider 10 did, so why not this one?
