Orsley gave me a set of these knobs to review. These grips make holding the Joy Cons much easier. My sister and I played Snipperclips for an hour with no problems. I know some people have mentioned weak shoulder buttons on these handles. The set I received turned out to be a newer version they just released in 2018. The buttons are nice and responsive when pressed; So it looks like all the issues people were having have now been fixed. You will know if you have new ones when it says "2018 new and improved design" on the box. I contacted them and they told me that from now on all stock should be this new version.
