Seem too small and uncomfortable for me, and those sticks are too "out of the way" and thumbs are not that long... Gonna stick with Joy-con's and get a Pro Controller when they drop in price.
The controller works great. I really really like it. Had no problems with it and it started right up with the switch. I highly recommend this controller. Though I do think it is better than a pro switch controller, it is definitely A runner up.
