This is an amazing little air compressor for inflating car/truck/bike tires. Mine just arrived well packaged and on time. I've used it on 2 cars and it worked perfectly - it took less than a minute to fill up each tire. I particularly like the AC function because it can be operated very conveniently via a garage socket. My old compressor was DC only and I wasn't comfortable using a car battery/cigarette lighter. I also like the screw connection. This is new to me and I already prefer it to the standard cam/lever type linkage. The gauge seems accurate as it matches the two hand gauges I have. I would recommend this product for light applications.
