I always keep a tire pump in my car in case I need to use it for a puncture or flat tire. I've had the same pump for probably 10 years now and it's finally close to biting the dust. I decided that instead of waiting for it to die for good (like I usually do with other items), I would be proactive and find a new pump to replace my dying old pump. I like and highly recommend this pump. It is compact but can be used for car tires as well as bicycles and objects such as balls or pool toys. I actually used the pump last weekend to fill floats for my girlfriend and her daughter when we went to the pool last weekend. One feature I had to get used to was that when measuring air pressure in a car tire, the measurement is in bar instead of psi. Not a big deal, but just wanted to mention it. Also, I really like the feature that allows you to set the desired air pressure and let the device work until it reaches that value. I will definitely keep it in my car and am very happy with the purchase. Would definitely recommend this tire pump to a friend.
