The spring loaded balls seem to fall out easily. One nut was missing the ball completely - none in the bag; neither the spring.These do not work properly in the more common 4040/4080 profile used by sim rig manufacturers such as NLR.From dimensions given these look to be more likely to be 3030 nuts.3 stars for low quality (or no QC) but will be sufficient if used with the correct profile.

They do the job. There was only 1 of them out of 100 that was bad (ball and spring came apart in package). Although I did notice some of them do not have as much tension as others, so in vertical situations they would just drop down. Most of them did the job though. For the price, I can't complain.
