There are seller on ebay selling these mosfets as "pulls", which to

Keep in mind you have no way to know an "ebay pull" is really a "pull"
from another unit vs. someone simply offering the same "dubious
provenance" part while stating it was a "pull".

I.e., the ebay seller could simply be offering the same dubious part,
with the "value added service" of applying a small bit of solder to the
pins to make it look "used" before shipping it to you.
