Good stuff
I got the M6S model and have found it to be a quality product, the default joycons don't have much to wrap my hands around so it can be a bit uncomfortable, especially in handheld mode, I purchased these to be a permanent replacement for the default joycons since they have gotten beat up over the years, official joycon replacements from nintendo cost about $80 but I got these for about $45, they are at the very least just as good if not better than the original joycons that came with the switch.
