I have fibromyalgia and this lightweight controller with the sensitive buttons is the only way I can play over 20min. It truly is a huge game changer. I feel like I have my favorite hobby back again and that is priceless. I originally got the switch buttons and it wasn't working out for me and they swapped them out no problem. I highly recommend to anyone with any kind of hand issues.
I emailed them about changing the evil sticks since they were too long and getting rid of the back buttons and they sent back the controller just as I asked. Very easy
