¶ Recommendation
Members of the community have generally regarded this controller with positive sentiment:
2024: Unevenness in build quality holds this controller back. If you get a good unit, it can be very good, but if you get a bad unit, expect the issues to be so bad you need to invoke the warranty.
2023: An all-around great controller with board legal turbo and fairly accurate sticks. Built for small hands.

¶ Turbo At a Glance

Tand press the desired button twice.

¶ Positive Sentiment
Very promising budget controller that checks all the boxes: great sticks, responsive buttons, accurate turbo up to 20Hz.
If you use the KeyLinker app, you can choose between 17 discrete turbo speeds.
Near-perfect sticks, face buttons are easy to press, and four paddle buttons.
¶ Negative Sentiment
Controller is very small, even for small hands.
Unable to use paddles from opposing hands simultaneously.
Paddles are rockers and not four discrete buttons.
Fast charging this controller, even once, has the potential to cause permanent malfunctions in the hardware.
I’ve had the controller drift multiple times but [the problem] went away when I took it off the Switch and turned it on and off.
