I was wary at first after seeing so many 5 star reviews but this pump is solid 5 star performance. I have a slow leak in one of my tires. Until I get a chance to inspect it I decided to get a pump to keep it properly inflated. It took less than a minute for my tire pressure to hit 5 pounds. It's quiet enough. It's mostly plastic and fairly light, but overall it's solidly built. I have an appointment for my first oil change in November and then I will fix this slow leak but I have filled the slow tire 4 times since purchase. this pump. It worked great and fast every time. One of the legs is missing for some reason, but that's okay! This is a good product. Update - I fixed my tire. I still use (and love) this pump. I use it to keep my spare tires inflated.
