The Elemnt has a longer battery life and I like the larger screen. If my Elemnt broke today, I'd get another one or possibly the Roam. I like the advanced navigation features of the Roam if it worked good. When you drift off course with an Elemnt or a Bolt you have to find your own way back. I always carry my phone and my area downloaded for offline so I have a workaround but that would be nice on the unit. I got my Elemnt on a random one day sale back in 2017 for $230 which was cheaper than the Bolt.
