Anyone used SLA5032? Does it work properly with Sigrok?

Hello

Anyone owns or have used SLA5032? https://sigrok.org/wiki/Sysclk_SLA5032

Is it a decent option?

I got curious how these saleae clone works, my question is just for education purpose. I mean, is there any change inside the hardware itself to emulate any specific proprietary communication? Or all they do to fool Saleae software is advertise their USB with ID of a Saleae device?

Thanks
