Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The clicky tactile switches feel so satisfying during gameplay, and I was surprised how easy the assembly instructions were to follow. Plugged it in and it worked perfectly on the first try without any tweaking needed.

Daniel ★★★★★

The thumbsticks feel incredibly precise right out of the box, and I love that the kit came with all the tools and extra screws I needed. It took me about an hour to put together, and the clicky face buttons are super satisfying.

Hazel L. ★★★★★

Assembling this kit was genuinely satisfying, and the fact that it boots up as a fully functional gamepad with all modern features right after building is a huge win. The included parts are well-organized, so even a first-time builder like me had no trouble getting it working.
