Apex Legends with keyboard and mouse

Hey, i am writting this post to ask you all about playing APEX with mouse and keyboard. I don´t find it very easy to play with a console controller (i am a more PC player but my PC is not good enough to play on it). I am considering to buy that adapter or to buy those keyboards and mouse for PS4/XBOX only, Am i the only one? I  know the game is new but i am trying to know if it works and if i am no wasting my money.

Anyone? 

Pls help me
