As a "photography is a cheaper hobby than a boat person" I am semi-shocked you even considered it for only about 6ish percent off...
Even Amazon sellers where there is a better return policy will happily try to pass nonfunctional stuff as working and hope nobody notices till after the return period.
(And that, actually happened on a 500$ used a6000. Looked like it worked gr8 till you tried to take a picture)
