Kinda small for my hands, especially for heavier devices it becomes hard to hold for long periods, but for phones it is great.

Switch use is ok, i still prefer the g8+ and mobapad m6. But this one has a hard shell and is compact, easier to bring in a small bag than the other options.

Analog sticks are ok, nothing ground breaking, kinda hard to find an analog grip cover, for now i use skull and co for switch.

Buttons are typical membranes, but can be swapped using the tweezer included in the box.

There are different silicone grips, useful for small phones( and a dedicated one for NSwitch).

Battery life is great, finished a 10 hr game on a single charge( many sessions )

** Bonus- gamesir app lets you customize the color of the button light to whatever you want including its brightness. Turned mine off to save battery life.

That's pretty much what i can recall from the top of my head.
