Is this PS2 universal stick good?

NO.

It looks like a clone of the old Mayflash stick.

so it’s not good huh? like probably feels shitty, shitty buttons, and doesnt work very well?

I would never buy that. From the looks of it, seems like a low quality, no name product.

It’s a clone of Honcam/Lioncast sticks. I would stay away from that stick.
