This kit is great for when you have to work on your cars or around the house. The thing I like the best about this kit is that it fits in my car taking up almost no space at all and I can feel confident that the kit has the tools I would need to do any repairs on my car during a trip. I had to purchase just two other size wrenches to throw into the kit to make sure I have all the sizes I need. You can probably buy around 15 extra size wrenches and they will store inside the carrying case. I don't go anywhere without this kit in my car. I have replaced my brake calipers, wheel cylinders, alternator, battery and many other parts on my car with just the use of this kit with the two extra wrenches while I was away from home. I've been using the same set for more than 2 years and I have not had a problem with any of the tools in the kit. I would definitely recommend this kit to anyone looking for a reliable set of tools to store in your car for emergencies. As with all Craftsman's tools, they have a lifetime replacement warranty if any of them were to break on you. It's a great set of tools at an affordable price.
