Review on DFROBOT Gravity: 1602 LCD Keypad Shield For Arduino - Simplify Your Arduino Projects with LCD Display and Keypad Interface by Jason Melvin

This sign does what it's supposed to. It's easy to integrate into a project and does what you expect it to. The build quality is excellent. I will say that the stack connector pins are a bit short. This makes it difficult to install a display with another screen, such as an Ethernet screen. This is easily fixed by inserting a second set of batch headers in between. Be sure to order them at the same time if you plan on putting them on anything other than a bare Arduino.
