Review on 🔵 Enhanced Visuals: JANSANE 20x4 2004 LCD Display Screen with IIC I2C Module Interface Adapter - Set of 2 in Blue by Kevin Abner

These displays are very popular and extremely easy to use with Arduino. They come with and without an I2C backpack. This particular seller is offering 2004 pairs (with backpacks) at a very high price so I bought two pairs. One of the units had a small problem with the backpack - it wouldn't turn on the LCD backlight, although the LCD backlight itself worked fine, I was able to turn it on by powering it directly from the edge connector on the 2004 PCB. So I emailed the seller (JANSANE) and asked for a replacement I2C backpack. and they sent me TWO NEW COMPLETE DISPLAYS (LCD screen and I2C backpack). In over 15 years of shopping on amazon.com I have never seen a seller respond so quickly and try so hard to make the customer happy - thank you JANSANE!
