Review on Renewed TP-Link Deco M5 2-Pack: High-Performance Whole Home Mesh WiFi System for 3,800 sq. ft. by Brett Bush

My home is a concrete block structure approximately 1868 feet tall. The internet router is in the common room furthest from the master bedroom where I had very little internet signal to watch TV or use my computer. I tried another expander but the results were marginal and inconsistent. I bought a TP Deco system and it improved signal strength by almost 80%. This is not ideal with this type of concrete structure, a third decorative protection module will probably improve the signal strength. So in applications like mine I would recommend three modules.
