I have a smaller compressor I've used for several years for my pcp airgun. I use this with a garden tractor type battery for taking in the field. I decided to get this compressor for home use and back-up for my older well used unit. I am impressed with this compressor. It is well made and powerful. The first time I turned the cooling fan on I thought it was going to fly away. It fills my gun quickly. I have confidence in this unit. After using it for over a month, so far I have no negatives to report.
