Quick service and responds after normal working hours. So hard to build a business, do the R&D, process and ship orders, respond to customers, deal with vendors, etc., etc. And Tim does it with a new baby as well.

Pretty amazing quality, service, and R&D. Thanks for being a pioneer in the Vmax community!!!!!
