I use this controller for Smash because my hands are very small. It works really well! I have both the wired and wireless ones. I do notice a bit of input lag for the wireless one, but the wired one has virtually none. The home button (for the switch) is very very close to the B button which causes my thumb to hit it on accident which is super annoying. Other than that, it's portable, light, and is a perfect fit for me.

This thing is absolutely great. It triggers the nostalgia factor, it works great, it has a ton of modes, including gyro. I've used it on a Mac, PC, phones, tablets, with emulators and every time it worked perfectly. The firmware is upgradable, on Android it can emulate touches, it's absolutely great.

Very good product! I bought it to use on my Nintendo Switch and it's awesome, easy to pair and easy to use! Really great for Mario Kart! Highly recommended
