****Update****10/26/2020At first I liked this product but after 4 months of use it stopped working 7-8 times. I emailed the company when I registered them at purchase but no reply yet. I bought this air compressor to inflate the airbags in my coil springs when we tow our horse trailer and it was very easy to use and accurate. After setting the PSI and inflating the airbags, I always check the tire pressure with a handheld pressure gauge and it's usually accurate. If I had any advice, make the power cord longer. This isn't a problem for me as my truck has a DC plug so I use that along with an extension to run it to the back of the truck where the valve is located. Overall, I'm really excited about this device.
