Anyone in the market for a high end compressor can rest assured that Alkin US takes excellent care of their customers. I have owned an Alkin 31 manual compressor for the past 15 months. Whenever I have requested information, parts, or service their responsiveness has been unparalleled. Ayden and David at Alkin take care of their customers and know their product line. If you buy an Alkin, it is good to know you have top notich support for your purchase.
