I can't really see yet that the cell booster works very well. I've been told you need to be really close to the interior antenna for it to work. Where I've been able to test, I get great reception anyways, and the same inside the trailer. Maybe when I'm out in the boondocks it will be more useful.
I did get one question about the metal foil insulation interfering with radio signals. So far I don't see any issues. I think with all the
windows, there is plenty of opportunity for signals to get inside the trailer.
The wifi booster seems to work well. My original unit had a broken power connector, but they sent me a replacement straight away and it was an easy change-out I could do myself. The new one seems to work well - pulled in 22 wifi networks in my neighborhood - more than I'd ever seen from my laptop.
