SazkJere Access-Control Keypads SJ64X4 Editorial Review
The 4PCS 4x4 Matrix Keypad delivers a mixed bag of performance and quality, as evident from customer reviews. While some users successfully integrated the keypads with microcontrollers like the ESP32 and RP2350, experiencing flawless functionality with customizable buttons, the overall reception leans towards disappointment. A significant number of customers reported defective units, with frequent mentions of non-responsive keys and a lack of tactile feedback when pressing the buttons. Issues with the quality of the connector strip were noted, with complaints that it could easily be damaged during soldering. Based on customer feedback, it’s clear that this product may suit those who are tinkering and testing but falls short for those seeking reliable, robust components in their projects. **
