The Hailege 5pcs 4x4 Matrix Array Membrane Keypad Keyboard has garnered mixed reviews from customers, highlighting both functionality and quality concerns. Many users appreciate the straightforward design, describing the keypads as standard and easy to integrate with electronics, particularly with an 8-way I2C port extender for applications such as keycode or remote control. However, a critical downside mentioned by several customers is the inConsistency in switch quality; users noted that the tactile feedback varies significantly across the keypads, with some keys requiring more pressure to activate than others. This inConsistency can lead to frustration during use, as it can impede reliable operation if the keypad is not mounted securely on a solid surface. Further, users have voiced concerns about the quality control of the products. One reviewer explicitly stated that none of the keypads functioned properly, highlighting an alarming level of dissatisfaction.

While the keypads do hold promise for certain applications, the overall reception indicates that buyers should exercise caution regarding the quality variance and attachment requirements before purchase. **
