yong heng trouble[[bottom line,no help or compressor]]

I also purchased one of the yong Heng Compressors , on the first use the adjustable pressure gauge went bang with a spark, i contacted manufactures and they sent me a replacement gauge, after about 6 months the compressor would only go up to about 300 psi i contacted the manufactured and was told they only had a shelf life of 6 months !!!, i removed the head and found a reed valve had broken after a lots of contact they finally with Aliexpress help sent me a link to buy a new reed valve, now after about 11 months it makes a venting noise once every few seconds , it still fills to pressure but does take a long time
