Hubs loves it
My husband works on cars all the time and often needs new tools, parts or fun extras. This is no different. He had zero complaints for this item. Said it worked for what he needed it for and was easy to use. He also works at a shop they often order things for work and this was one of them. Shop approved it and appreciates it.

Bad quality control
Not gapped correctly. The quality looks ok but they are supposed to be gapped to .044. I measured all of them and I got measurements from .020 all the way to .040. None of them were where they were supposed to be.

Theses are legit NGK for this price
Identifiers of copy vs. Legit. 1. sharp angles on caution triangle in the back. Fakes have rounded corners on that triangle. 2. Manufacturing stamp on the facet of 5/8 nut area. Fakes have none. 3. The arc of the lead to the tip on fakes are angled, the lead on the legit ones are square with the threads. 4. When you get them, put them on a multi-meter. You should get consistent resistance between all 6 plugs. The fakes are wildly inconsistent. These passed on all 4 counts and even came with a seal of authenticity.
