To be honest, I don't normally use spice packets. This isn't because I don't like them, but rather because since I have such a large variety of spices on hand, it only makes sense for me to use what I already have. I think packets are great though for people who don't keep a lot of spices and for them to have to go out and purchase seven or eight different spices just to try one marinade, doesn't make a lot of dollar sense. These Amazing Taste packets are only $.99 each and for that reason alone, I endorse the usage of them.
I used a marinade recipe that they included in my package. It's a very simple marinade using the packet for beef, a quarter cup of olive oil, a quarter cup of water, beer, or wine, two tablespoons of soy sauce, one tablespoon of Worchestershire sauce, and two teaspoons of coarse black pepper. Marinate for at least fifteen minutes and then grill.
