McBazel KX Keyboard & Mouse Converter Adapter for Nintendo Switch, PS4, PS3 - Play FPS Games Like a Pro on Console with PC Peripherals

This is a long and detailed review about testing it on the Switch only; but I would think one would get the same results on the other consoles. This does work on the Switch if you set it up correctly from the instructions (which is not difficult at all). Basically this device fools the Switch into think you have hooked up a wired gamepad where the keyboard takes the place of some buttons while the mouse takes the place of the other buttons (none of which can be programmed as is but keep reading about mouse usage). However to get the most functionality from your mouse I would recommend one that has internal/onboard memory and a computer so you can setup the buttons on the mouse first using the software for that mouse on the computer to match the buttons on the gamepad that you want and then use it on the Switch. This will require you to look at the instruction booklet and see which keyboard keys emulate which gamepad buttons and then assign those to the mouse. This way if you want the back button on the mouse to be the Y button for example you can set that up on the computer and the mouse will keep that setting when using it with the Switch. If you do not do this and use everything as is then the mouse will be limited to the right, left and middle click (the scroll wheel) because the back and forward buttons do nothing and of course you can still aim/look around using the mouse. Having said that though the rest of the gamepad buttons are all emulated on the keyboard; but this requires you to do a lot using your none mouse hand. Think of it this way on a gamepad the buttons are divided between your left and right hand while using this setup by default puts more buttons on one hand than the other. Did not notice any lag when trying it out on the game Spellbreak in practice mode, or Doom in arcade mode. Using a mouse is definitely more accurate than using a gamepad even with motion assist; but there is a trade off since learning to use the keyboard requires different/more muscle memory but this is mitigated with a programmable mouse. Keyboard wise it worked with an old rubber wired USB one that I bought a long time ago; but that is the only wired USB keyboard I have to test with at the moment. So at the time of this review I cannot recommend a keyboard only confirm that it does work depending on the keyboard. I am waiting on a newer wired gaming keyboard that I ordered that another reviewer said works with this device so I can use a more comfortable keyboard since the rubber one has weird keys. I have provided Amazon links to the mice I have tried and the keyboard that I ordered.Works with any of these 3 mice (yes I tried each).PICTEK: (least amount of buttons cheapest price)https://www.amazon.com/gp/product/B00RH6R7C4/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1Logitech G300s: (middle number of buttons middle price)https://www.amazon.com/gp/product/B01FZ3BR5S/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1ZLOT Vertical: (most amount of buttons highest price)https://www.amazon.com/gp/product/B07T3PFWCB/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1Keyboard that may work with this but cannot confirmhttps://www.amazon.com/gp/product/B07HHZ81FW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
