PCMAG EDITORS' CHOICE -- BEST HOME CELL PHONE SIGNAL BOOSTER

“[After installation] Everywhere within my house I had full service, and I maintained 3 and 4G the whole time... living in a rural area in almost the middle of nowhere this thing is a must have when service is spotty. Plug this in and set it up, and it does wonders.”
– Brooke K, Flare Customer
