No problems with fit finish or quality of construction.
These were used to connect waterlines to a refrigerator. They worked as expected.

Exactly what was listed in the advertisement.
It did take a little while to get. But just a few days more than regular Amazon packages.

Not made to industry standards but will work if you don't need that.
These fittings are OK and the company is really good on customer service. The NPT side is machined slightly small and has to be turned almost to the top thread to bite. The tube side nut and ferrules are not interchangeable with standard industry tubing fittings such as Swagelok or Parker.
