    If you have a GameCube controller, this is a no-brainer

    Honestly transforms my usecase for the GCC completely. I can take it with me portably + have it connect as a tiny dongle off my USB C port directly. It's also so much better than the native Switch or Mayflash GCC adapter in terms of latency.

    Best slippi Emulator adapter

    Unironically 10x better than may flash adapter in terms of input reading and latency. Went from being unable to move efficiently to a Master Ranked grinder. 10/10

    Not suitable for competitive smash

    It works great, is very cute and it has various modes which is useful, although I only needed the GC one. But then, I realized. It sometimes stops registering new inputs for 1 second. This has happened to me in different systems, both switch and PC. It happens VERY rarely. Like once in a day, maybe twice, sometimes none. And is only for one second. I was not going to post this review cause I think it works perfect for anyting else that isn't competitive gaming, but kept getting a mail asking me to do so lol.

    I didn't have any trouble when putting it together, it didn't get any hits, everything was looking perfect when it arrived. I dunno what caused this, or if it happens with every product. I don't mind, I'll just use something else for smash, and I can't bother sending it back cause I'm from Europe.

    Thanks for your review! Please reach out to us at support@handheldlegend.com so we can discuss this feedback further.

    Awesome portable adapter!

    The device works great! I use it for both Switch and PC, for competitive play. I look forward to further firmware updates.

    Works perfectly with Dolphin!

    Agree this is the final form GC controller adapter. Simple assembly, amazingly intuitive web-based firmware update and config mode. Was confused at first that it didn't immediately work with Dolphin. Then remembered I needed to use Zadig to replace the USB driver from the much bigger and unwieldy Mayflash adapter I'd been using. After that it worked perfectly, and I honestly feel like I notice a huge latency improvement playing Mario Golf. Just excellent all-around work here guys, thanks for making this product!

    Not much to say other than that it works great! I love the mechanism for pulling it in and hit
