Review on SolidRF Cell Phone Booster for Home and Office – Signal Plus Cell Signal Booster Kit, Up to 8,000 sq ft Coverage, Dual Interior Antennas – Works with Verizon, AT&T, T-Mobile, Sprint, and More by Dan Cramer

At first, it strengthens the incoming signal, but after 3 days of use, the flow is not stable. I'm not sure if 5g isn't already a very good 4g. . The best signal is 2 bars on mobile most days. I use it in an all-metal building with an area of about 2000 square meters. m with a transmitter inside, can't support 4g, yes 3g. For the price I think it's ok, I bought another type from BB and paid another 300€, which is almost as good. I would buy another. Probably no.
