The first unit I received didn't appear to work (refurbished) but the company was responsive and suggested I contact WeBoost directly since they couldn't replace it.

If the unit was cheaper I would have given it five stars

And, as others have noted the unit runs very warm.

This unit works very well in our camper and in our home

Worse, after being plugged into power for anything more than 30-45 minutes, the unit gets so hot you literally cannot pick it up

I have tried to see if there is a meter or something I can use to determine if the unit is working, nothing

The unit I received was faulty with trouble lights on

I called Customer Support to see if I had an abnormal unit or if there was some magic ritual involved in installation, but that did not help

Ensure keep the indoor unit cool by putting it near your airflow or protect it with some kind of shielding.

This unit does extremely well when there is an existing signal to boost
