Manhasset Voyager Music Stand

I own two of these stands but had to receive 4, because each purchase required an exchange. The first two had a defect where the inner shaft fell into the outer shaft and the nut was on very, very tightly. I had to get someone else to help with the assembly where he held what tiny bit of the inner shaft was sticking out while I tried very, very hard to turn the nut and eventually succeeded. Our grip on the inner shaft kept slipping, because of how little was accessible, and the nut was on very tightly. However, once the shaft was attached to the tripod, I found the stand great to use. The second two I received both had looser nuts and the shaft had not even fallen inside on one of them! However, on the first of these two, the place where the shelf attaches to the shaft was defective; I could not turn it much and could only get it halfway tightened even with the aid of a hammer. The exchange stand has similar problem but not as badly, because it can actually be turned, if with a lot of effort and more force than my other stand. Both of the second two stands had rough edges to the tripod part such that it actually cut the surface of my skin. I really like the Manhasset Voyager stand— it is sturdy and like having my regular Manhasset stand for gigs!— but I find it ridiculous that 4 out of 4 stands had defects. And some defects were severe enough to prevent assembly of the stand.
