Compared to a cheap $30 version, this adapter isn't much better. Both adapters look nearly identical, like they've been plucked from the same assembly line. The K&F adapter might have a very slight advantage in build quality, but that could be down to random sampling. Both adapters are loaded with lubricating grease and have a similar 'wobble' when turned.
I'm not sure what I should be expecting when the K&F is twice as much as the cheaper one. They both work but can bind easily and don't feel very confident. I usually like the K&F adapters for their good performance and good price, I can't say the same for this one though.
