As for Android, it works great using Note 3 perfect size and clips on fine and playing Minecraft works great.

The size of the controller feels right

compact size, but still ok for my man-hands

I like the size and portability of the controller but they only work with certain games.

It still feels comfortable in my hands, but the smaller size makes it more portable

It's light, sized just right for playability and portability, affordable, and despite less than perfect responsiveness is still quite fun to use.

The controller is a good size and a fits in my hand really well

I have average sized hands and its slightly uncomfortable.

It holds my phone (Galaxy J7 for size reference) nice and securely, weighs nearly nothing, and the buttons and the joysticks seem very well made
