I've had good customer service from Stigma, but I don't use the Hyper. I had to get new motors in my old Bizarres after using them almost exclusively for 3 1/2 years...and no doubt also getting some liquid into one of the motors. They were possibly a tad grumpy about the details of the service, but quick, efficient and fair, and they were fine repairing a machine they don't even build anymore.
I might be a little loyal to Stigma, but hopefully not biased. I just wanted to put in a good word for a company I love.
