Shitty thumbsticks that are wobbly and have issues with clicking in. A completely pointless and useless touchpad that almost zero games make good use of, a system button that is located nowhere even near your thumb. Finger tracking isn't all that great and is actually annoying to deal with in a lot of games that support it where you're constantly accidentally doing things just by having your fingers by your controllers. A grip button that doesn't even squeeze in when you squeeze it, so there is no feedback when you're actually squeezing something in VR. A design that tries to be ergonomic but fails overall when compared to Touch controller, especially in regards to thumbstick placement and curvature of the controller in your palm.

Overall while I wouldn't call the Knuckles/Index controllers a disaster, and would say they're definitely much better than Vive wands, they're still incredibly disappointing, and to me personally the Touch style controller that everyone is copying from Cosmos to Pimax and WMR, is the way to go. The only downside is you have to hold them whereas Index has the strap.

The strap is definitely the best feature of the controllers, but also one of the things that makes it less ergonomic since it kind of forces your hand into a certain, kind of rigid position.
