Review on 📶 FourSeas 4G Cell Signal Booster for Home - AT&T/T-Mobile/Verizon - Dual Band 2/4/12/17 CDMA/LTE FDD - 65dB 1900Mhz(Band2)/1700Mhz(Band4)/700ac(Band12)/700bc(Band17) by Christian Barnes

Wow, what a waste of time. Setting up these things isn't exactly easy, so it would be nice if it did at least one of the things it's advertised to do. I usually pack them well when I send them back, but I think I can just put all that crap back in the box and let them sort that out because they spend so much time setting up a product that doesn't work. The instructions were for a completely different device. It didn't even try to boost volume 2. The signal it sent out on December 17 failed to transmit data - I had to turn off the device to regain data service on my phone. All of these 5 star reviews should be rubbish - keep looking - this is not the one.
