As described. Satisfied with this product.
I used this to support an 8 mm z-axis lead screw for a 3D printer. This is not a demanding application so I think it will work very well. It fits easily over the lead screw. The outside diameter is exactly 12 mm measured on a digital caliper. The length is 9.9mm also measured on a digital caliper. The rollers move smoothly.

Significantly undersized, very loose fit.
Thread major diameters were between 4.6 and 4.7 but should have been in a range of 4.874 to 4.984 so they were very loose fit. Other than that the head was well formed and there were no obvious defects.

Works for NS4300N with modifications
I bought this to replace the power supply for a Promise NS4300N as noted in the product description. This supply has unnecessary extra cables for floppy and eSATA (as noted in the description) so I ended up cutting those off to fit easily in the case. I also compared the 24 pin connector with the original connector and cut any lines that were not on the original, except for the extra +5V red power lines. e.g. -12 volt blue. The power supply fit perfectly into the Promise case and has powered it without problems. Other replacement supplies without the extra power cables cost two to three times as much so good value.
