Correct you buy the item and they refund you but they dont force to do anything you don't want, weve had inkbird for a long time they are not asking for 5 star reviews they are asking for legitimate ones,
We've had no complaints on refunds
Amazon will not let you review anything unless you actually buy it, this is how they ensure they get a review, its a roundabout way for them to get more popular in amazons search engine.
you still get free product, it helps the company.
You dont have to do that at all if you dont want too
