It's a high dollar set that you get what you pay for!!! The 20,000 mile Warranty proves that they're willing to stand behind their products for a great amount of time. Each piece of the set is a heavy-duty and well built, giving me the satisfaction that it was more than a good purchase!! I placed my order over the phone with a Dennis Kirk's representative, she was so Pleasant to work with. I'm usually one to ask many questions and she kept right up with me answering All of them and in such a pleasant way !!! I highly recommend Dennis Kirk and WILL BE CONTINUING TO USE THEM AGAIN!!!!
