Awesome controllers, not only for small children's hands (ideal), but also for mine.
Remarks:
- Each controller has different charging cables depending on the color!! (*on their connection port with the controller, the other end is USB type for both). I bought a Turquoise and a pink one, and they have a different type of connection with the port on the controller, meaning they are incompatible with each other!!
- Also, for their "recognition" by the Switch/Switch Lite, read the instructions they have. If you read them, it's very easy, but if you go (like I initially did) without reading them, you will most likely fail.
Overall, very nice controller and very nice construction and easy to use, but pay attention to these details I mentioned.

I personally consider it one of the best portable controllers available. It is the best for Gameboy emulator on mobile. You can play the entire collection from the first Gameboy to the DS. Very easy pairing. Very long battery life. As for the size, the buttons are like GBA SP but of higher quality, and the casing is as small as it needs to be for portability (it can be difficult if you have large hands)

I use it on Nintendo Switch Lite, it connected easily, it brings good quality but it is very small and uncomfortable

I bought it for my 5-year-old to play Mario on the switch, he loves it. It is comfortable, the battery lasts for months, and it only takes a few minutes to charge. It is worth it for a child, do not get it for adult use.

It's fun, cute, and well-made. Obviously, it's not for everyone, but it's great for various platformers. I recommend it to those who have the Switch Lite

For a child, it is good, but for an adult, no! It is excessively small. I connected it easily to a PC, but I couldn't manage to do it with the Switch, but it might be my fault.

It's simply perfect! It's much smaller than I imagined, but I got it for my 7-year-old daughter, not for myself. Its quality is on par with a genuine console controller, and its response is immediate. I use it with a Nintendo emulator on my tablet, and it's excellent. Despite being tiny, I can still play with it. It's also very important that it's rechargeable and doesn't require batteries like cheap controllers.
