"My Maingear Shift was 6 1/2 years old when I called for customer service this year. The team helped me with the problem, which was really a Windows 10 issue. I spoke with the head of sales and we concurred that, with a small upgrade, my Shift had another year or two left in it. The machine remains faster than the Dells we bought recently for my company, although my new Dell 15" Macbook Pro 15" runs a bit faster for some massive Excel spreadsheets.
Overall, the longevity and reliability of my Shift remains amazing, the "Angelic" service, incredible. Note, I've rated my $4,000 Shift low price because I've retired a handful of new laptops and desktops since I bought the Shift 7 years ago."
