I bought the DeWalt 204 Piece Mechanics Tool Set at the recommendation of my father-in-law who is a professional mechanic. He would be my go-to guy for our family's cars except that he lives more than six hours away. I have had too many bad experiences with dishonest mechanics for minor issues and even major ones. Whenever possible, I wanted to be able to fix my car myself. I was also hoping to learn how to change my own oil, tires, etc. He recommended this kit, and I have really loved my other DeWalt products, so I bought the entire kit. I have to admit that it was a bit overwhelming and still is for the average car owner like me. However, I have found that every single piece that I could possibly need is in this set. I am still learning what many of the various sizes are for, and I'm not sure that I will ever use all of them, but I'm happier to be prepared. The hard case keeps all of the items protected from dirt and water and even dropping. It is a bit bulky, but it neatly keeps everything organized and within easy reach.
