Betaone Computer Repair went above and beyond the call of duty to diagnose a recurring problem with my computer. I give them exemplary scores in customer service, integrity, and response time. Despite all of their testing, monitoring, and analysis, however, the problem remains. I am hopeful that they will continue to research the issue, as promised, and that they will ultimately find a solution. If that should occur, then I would give them an unequivocal 5-star rating.
