The dealer basically wanted to charge me $6.00 to replace a nut on my car. As it turned out, I was able to buy and replace them for a much cheaper price. Although I didn't have to replace everything, I went ahead and did it. I was amazed at the packaging of this product. It can be said that quality control is a key issue for manufacturers and sellers. In other words, the packaging showed that the seller (manufacturer) took great pride in their product. Since I contacted my car I haven't had any more problems. I have checked the tightness of the lug nuts twice since applying and they remain true. There are no issues to report. Item looks like Amazon and works as expected. There's nothing more to say about that. Thanks for saving me a hundred dollars!
