I like that it works. The pressure gauge is wrong, I need to set it 8psi higher than my car requires to get the correct pressure. 4 stars for this reason. Besides, it works fine. It turns off when it needs to be read. It doesn't overheat. The power cord is long enough to wrap around the car and the coiled tubing is great for extra reach. It's easy to store, doesn't need the hassle of packing neatly into a storage bag, isn't too big to hide under the seat, and takes up a fraction of the trunk's space. I am not disappointed with this purchase.
