The GPIO hookup on my 2.8-inch screen was finicky before, but this adapter made the connection rock solid in under five minutes. It slots in cleanly and I haven't had a single loose-pin hiccup since.

Took a chance on this for my 3.5-inch Genius and the fit is spot-on—the GPIO pins click in snugly with no wobble. Wired it up in under five minutes and it’s been rock solid since. Exactly what I needed for a clean setup.

The GPIO header lines up perfectly with the board’s pinout, so wiring took me under five minutes. It’s been rock-solid on my 3.5-inch display for two weeks now, no loose connections or glitches.
