Usually i avoid autozone like the plague knowing most of their parts are junk but i was heading out of town in a few days and wanted to check my a/c refrig... the so called expert recommended one of the products they sell that is a can of refrig with a hose and a gauge... you plug it in, read the pressure and if its low you pull the trigger and add until full... sounds easy enough... so i pay over $50 bucks for this can with a gauge... plug it in... GREAT... pressure reads full... thinking to myself i can use this to check my daughters car... then i unplug the connection and hear my port hissing and spitting out compressor oil... great... now i have a leak thanks to the piece of $#*!t the autozone expert recommended to me... when i confronted them about what was happening they had the nerve to tell me "nothing we can do about it, you will need to take it to a shop and have it fixed" NO... How about this... how about i just tell you and your piece of $#*!t company to go pound sand and spend my money at a reputable auto parts house.
