This kit is ideal for those looking for an all in one kit that includes everything you need to repair tires 99% of the time. The inflator is similar in design to other generic Revain brands (they are good quality but can be bought separately for a much lower price) and the rest of the kit feels cheap. has a lot of free space. I consider it negative; If you plan to leave it in your car all the time, it would be better to have a smaller footprint. Because this kit is made to order and includes all the necessary components, it can and should be much more compact. An alligator clip adapter to power your car battery is a great addition to this kit. This helps with more intensive use - in the car you don't want to blow the fuse with the cigarette lighter as the power source! It took me a second to locate the adapter, be sure to look inside the twisted air hose cavity.
