I bought a PCP air rifle and started researching compressors, because I didn't want to go the scuba tank refill route. I couldn't believe how expensive most of the compressors I looked at were. Most were double the price I paid for my rifle. I came across this Vevor unit and figured the reviews would be lousy, based on how inexpensive it was. I was very surprised at all the solid reviews on this one, so I went ahead and ordered it. I've only been using it for a month, but so far it's been great. Fills my rifle to the selected pressure and shuts off automatically. I haven't had any overheating issues or leaks. It's built very solid, unlike some of the cheap junk from China you'll find on other sites. It does exactly what I need, every time. I would highly recommend this compressor to any PCP shooters who want an affordable, reliable way to fill their guns.
