I like playing in handheld mode and I think it's a good alternative to Joy-Cons when you're having trouble. Enable wired communication with the professional controller and the switcher will recognize it as a professional controller. The product itself works quite well in my opinion. The rumble isn't as smooth as Joymins, but I guess that's to be expected from third-party controllers. The strange thing is that the manual is difficult to read, it's not translated very well and you have to think about what it wants to say. The company's website is also missing sections of the page that say "No Information," so you'll have to take the product as is, with few support options. So far this hasn't been a problem for me as it worked right out of the box with no issues. It takes a while to get used to because it feels a bit larger than a regular controller, but it didn't affect my gameplay.
