Different fin shape from original.
I don't know why some people here gave good feedback. I received a module that was PAINTED in silver to hide it was old and mistreated (and everyone should know that paint is not a good conductor both thermically and electrically). Nevertheless I mounted it on the transmitter to test if eventually it was working. Results was power almost zero and severely distorted output wave, so I received a faulty, old, reworked to extend pins component, advertised as new & original. Fortunately Aliexpress refunded me completely. Seller didn't even answer to my message.
Today I opened the module and checked the internals. This is an original (used) M57727 module, removed from somewhere, opened, pin extended, glued again and painted to look new. During this "refurbishing" process the functionality has obviously not been checked: in my case both the driver transistor and the final transistor have the base-emitter junction shorted. Someone might have been lucky and received a working module... In any case it's not at all a new-old-stock item.
