Oh, Nintendo, why did you do this to us. Why did you ruin the d-pad in this otherwise amazing controller...
Without any doubt it's a ton more comfortable than any JoyCon grip (although not as colorful unless you opt in for something like a dbrand skin). The pairing process is super easy and the controller is ready to use after a quick charge.
The biggest difference you'll notice at first is the weight - you actually feel that you're not holding a cheap controller but rather a proper, premium one. Well-balanced with sharp HD rumble and great joysticks, topped up with comfortable (z)L/(z)R buttons, this is a great upgrade for my couch gaming sessions. The grip is great too and battery-life is longer than JoyCons. All buttons are bigger, too.
It's just that d-pad that ruins it for me and makes me take off one star.
Can highly recommend for your couch sessions alongside any of your JoyCons (and grips) and I've only just played for a few hours with it.
