It’s one of the WeBoost units (don’t remember the exact model except that it wasn’t the one that only works within a few feet.)
I dithered with my decision the entire time I was at the rally facing poor cell signals, and finally bought it on the Friday. It definitely made a difference at the rally when I tested in their rig, but as it was the last day, I didn’t actually try it in my rig there.
Since then, I haven’t camped in any poor cell coverage areas so I haven’t tried it out other than once in the driveway. And that time, because I turned it on in a good cell area, it went into a feedback loop and locked itself out.
We’ve got some remote trips planned this year, so I’m hoping to finally justify my dithered impulse buy.
