UGREEN Bluetooth 5.0 Transmitter Compatible for Nintendo Switch

I got this for a retro handheld console (Powkiddy RGB10S) and it's worked really well for that. Both charge using USB-C. The battery life for this little thing is acceptable. It sticks out the back a bit. Not quite doubling the width of the device, but it's not pocketable when it's installed. But it's easy to take on and off. So that's not really an issue either. Additional benefit of this is that it can fit on other retro handheld devices (even an original Gameboy if you turn it around and have it show on the front instead of the back). I'm sure there are more flexible designs that would fit more universally, but I think this is a good middle ground between form factor and flexible fit. Areas for Improvement I would like it more if it wasn't such cheap-looking red/blue color. Black or gray would be better. A battery indicator would also be nice, but I'm sure that would increase the size. The flexible joint is really nice. It gives it some good solid hold on the Switch, the retro handheld, and the Gameboy. If there was a way to build the joint so that it could turn 90 or even 180 degrees that would widen what it can be used for.
