I’d say, if you get one, go for the Drive 4G-X OTR or passively the Drive Reach OTR, I went with the sleek version and while it does boost the signal, I think the premium tiers would do a much better job at it.
In addition a huge drawback of the sleek version is that cradle that your phone needs to be in drops your phone as soon as you hit a bump. Not exactly ideal when you’re on the trail.
