Cheap (prices starting from ~$8) fashionable USB gaming style mouse.
Switchable 800-2400 dpi, though it seems like wider range when tested.
Not quite matching picture on the box and some other pictures I've found on the Internet - side panels mounted with screws and style of these side panels is different. They are purely for decoration and I would not recommend as plastic underneath would not survive repeated reassembling - some glue might be needed then.
As there are some holes under big sticker on the bottom side (see cross cut below) I though at first this is where screws are hidden, but they are under feet.
Fortunately mouse is easy to disassemble after removing these four screws at the bottom.
Single all-in-one chip: SPCP180-126.
PCB marking: TY_V300_SPCP186 20180906.
Piece of steel adding weight.
I do not recognize brands of these switches.
There is some space for extra switch under DPI +/- button and there are also two pegs sticking from top part of the shell. Perhaps there was some variant using it.
Mouse was completely dead when I've received it, it was probably product returned to Amazon. Surprisingly this was easiest fix ever - USB cable plug was not attached properly.
H13 scroll encoder.
Three RGB LEDs seem to be some kind of "smart" 2-pin diodes, perhaps pulse controlled: https://www.youtube.com/watch?v=gxdgRHmOuIo
Special switch for mouse wheel.
Other minor issue: scroll wheel was slightly blocked by pieces of cable insulation (I've cut it off).
Mechanically this mouse seems similar to
