I've used this a few times so time will tell how long it lasts. So far, the product has worked flawlessly when inflating car and bicycle tires. It has both a car adapter and a rechargeable battery, so it can be used with both mains and battery power. The LCD display is easy to read. The only problem is the packaging that could be improved, the storage box might not stand up to frequent use as it's just a cardboard box. I would love it if it came in a hard plastic box.
