I cant say enough great things about Mr. Boyer, absolutely the best! I had him out to do a repair on our treadmill, an issue that has been going on for months in which another company/technician could not fix, and Mr. Boyer came out promptly, correctly diagnosed the situation, got parts quickly, and took care of the issue. He was on-time, courteous, and very knowledgeable. You will not be disappointed with him and the Quantum Service Company! A+ all the way!!!
