Unfortunately, this is a very fragile product that broke fairly quickly. Initially, the device could hardly fill the tire. The stated inflation time is unlikely to be less than 3 minutes! Starting the engine helped, but he still couldn't make his allotted deadline. Then the hose inside the block came loose. After disassembling it, I was able to secure it with a clamp. Eventually, the nozzle that bolts onto the tire started leaking, which was the last straw. Due to the fact that it could not be repaired, the device became unusable and had to be disposed of. Used a total of 7 times.
