Review on 📶 Ultimate Cell Phone Signal Booster for Verizon AT&T T-Mobile 700MHz (Band 12 13 17) 4G Cellular Repeater LTE Mobile Phone Signal Amplifier Kit 70dB – Amplify Signals up to 4,000 Sq Ft Area (Home and Office) by Elton Luo

Received the booster kit yesterday and just installed it in the attic this morning. Installed a yagi antenna on the inside of a 2x4 in the attic and pointed it at the nearest Band 13 tower, moved aside some loose insulation and placed the inside antenna on the drywall about halfway down the house, switched the amplifier on, saw solid green, went downstairs and saw the signals - 70dB sweet spot and -92dB at the edges of the house. Hooray! There are no comments on durability yet. I'm also wondering if a ceiling antenna would work better - just wondering because all is well again. Calls in areas where they used to have a good signal. We thought it was her phone and replaced it with an iPhone SE (new version). It didn't help. After speaking to the neighbors, we learned that they also have weak Verizon signals.
