Review on Micro Innovations CPQ23NKP Calculator Keypad by Walter Chavis

This keypad is not worth the investment .Through trial and error, I found that it is unreliable and slow. The only pro is that it is compatible with most commercial access control systems. However, the cons include poor construction quality and lack of durability. It's important to invest in industrial and scientific products that can withstand heavy use and abuse, something this keypad cannot handle. Don't waste your time or money on this underwhelming keypad..
