4.5 Star: half star lost due to some of the cons listed below.
Great device for connecting a variety of controllers to your Nintendo Switch. Allows connection of non-Nintendo controllers to the Switch.
Pros: - enables use of some PlayStation, Xbox and Wii U controllers on your switch. For a full compatibility list refer to the manual on the Mayflash website - simple connection and recognition by PC/MAC - simple firmware update process - no latency experienced on connected devices - great way to play local multiplayer with other controllers around the house - acceptable build quality - fits in USB port between hidden connections at the back of the switch dock - coloured LED light to easily identify connection mode - has its own USB port to connect a wired device. Also helps with initially pairing wireless devices that need to be wired to pair first eg Dualshock 3 - comes with carry case - comes with OTG cable in the box so that it can be used when Nintendo Switch is in portable mode. - price
Cons: - connecting controllers can be a little fiddly, however refer to manual on how to connect different controllers to adapter. - can really only properly use one controller at a time with adapter - mode/pair button on adapter is extremely small and can be tricky to get to when plugged in back of switch dock - aesthetics is not its strong point
I purchased this to use an Xbox Elite Controller with the Nintendo Switch. It works well, it's easy to set up, however the instructions in the box were pretty useless. A quick Google search provided set up instructions that were incredibly simple.
For casual games like Zelda or Mario, this is recommended. But for fighting games which require near-instant inputs, I cannot recommend, the latency is just too high for it to be usable. I was using an Xbox One S controller, used both wired and wireless settings and both had latency that wasn't viable for quick actions.
Worked fine for Breath of the Wild, but Crash Bandicoot N-Sane Trilogy bugs out in Switch Pro Controller (purple LED) mode. Controller is always vibrating, even when turning off controller vibration, so it's unplayable. Possibly other games have compatibility issues.
