Everyone I ride with owns Garmin products, I don't hear many negatives. My Garmin Tri-watch is pretty awesome. The issue I hear the most is battery life related, mostly with watches. If you're getting short battery life it could be setting related. I haven't had the problem myself so I don't know first hand but I've heard getting some help with setting up the watch/head unit can make a big difference in battery life. One cool feature on the Bolt, when it gets down to a low level of charge it will notify you it's going into power saving mode on its own and shut down everything non-essential so you can finish tour ride.
