We've been using a Max Amp RV booster repeater for over a year now, and have been very satisfied with it. The Max Amp has given us usable 4G/LTE signals even in places our previous WeBoost Drive 4G-M could only provide 3G or nothing at all. Since installing the Max Amp, we have not been anywhere that we didn't get a good signal on either AT&T or Verizon. Sometimes one better than the other, but both have always worked. We particularly like having the signal repeated throughout the entire length of our motorhome, instead of needing to be within a few feet of the WeBoost's "Hershey bar" inside antenna.
