So I gotta say I was very skeptical when I received this item. It appeared cheap and as it was described to me"plastically". I've used the air compressor several times with no issues and I've had it for about s month now. Last night while at work I had the opportunity to use the jump start on a work vehicle for the first time. I hadn't fully charged it in weeks and I gotta say, the moment the terminals were connected the lights came on and the vehicle started right up with no issues. So far I would definitely recommend this product. Caveat the coworker that described it as "plastically" ask me for the Amazon link and is now getting ready to purchase one
