Need your opinion – getting first sales from family and friends

I’m about to launch my product on Amazon and I planned out several family and friends to purchase the product after searching for the keywords (not from a link), spread out over 10 days. I will later reimburse those purchases, and I AM NOT asking them for anything else but to purchase. I just want the algorithm boost for the initial sales so that Amazon will show my listing to more unique customers.

Is this strategy legit? Anything I’m missing?

Would love opinions and experiences.
