Emily ★★★★★

The 20x4 layout is perfect for showing more data at once, and the white text on that blue backlight is genuinely crisp and easy to read from across my desk. Took a minute to wire up, but the I2C interface means I only used four pins and it worked on the first try.

Andrew ★★★★★

Had to adjust the contrast settings a bit on my first try, but once dialed in, the 24-character lines are crystal clear and make a huge difference over smaller displays.

Avery ★★★★★

The blue backlight is bright enough to read easily even in my dim workshop, and the I2C wiring saved me a ton of GPIO pins on my project. Setup was quick once I found the right library, and the contrast is sharp right out of the box.
