Great adapter, best price I could find - $12 used. Unlike others that were more expensive, this one is mostly/entirely metal as far as I can tell, making it very durable. Both ends are tight with virtually no play. Only criticism is its length and weight, I will never understand why many of these adapters are so long, but that is mostly unavoidable with F to E mount adapters. Note that this is a dumb adapter and therefore does not transmit autofocus signals. I recommend using it with vintage lenses that don't have autofocus anyway (like my $60 Nikon Nikkor-S Auto 50mm F1.4) and if you're comfortable with manual focusing.
