My Skull & Co. grip arrived today so I can start to enjoy my Switch at last. (Curse my large hands).
It comes with three different grips, of which I use the biggest one, though the one down is useable too and has kinda index finger rests.
Those were ready attached and were creaky at first, but the components weren't seated correctly. A little press and it clicked into place.
Sticking with the biggest for now.
They are very easy t swap over by simply sliding them off downwards and sliding the replacement on.
Supplied are little pads to increase the snugness of fit, I haven't needed them.
It is also adjustable to fit the original Switch by removing a few screws on the rear, removing a thin shim and reassembling. Easy peasy.
Won't be getting the updated Satisfye now, especially with the guessed specs that resulted in big gaps with fins to insure it fitted.
