MUZOCT IIC/I2C/TWI Serial 2004 20x4 LCD Module Shield For Arduino UNO MEGA R3

Per earlier reviewer, it arrived without the I2C board - which is clearly shown as being attached on the photo. I tried with my own I2C board (without soldering-as was thinking about returning the item due to mis - description). One character appeared to not display properly. I then noticed that it made a rattling noise under the LCD screen when moved , suggesting that something was loose between the screen and the PCB board. Have returned to Amazon.

I2C interface board not sent.I soldered header pins on LCD board before I realised the interface board was missing ...No time to fiddle about sending it back etc ...
