Customer Voice

  • ★★★★★★

    They have a lot of phones in really good condition. MCT’s grading standards are tougher than anywhere else! Honestly, their B grade is like other companies’ A, and their A grade is basically everyone else’s A+

  • ★★★★★★

    I actually got to see their grading line in person, and the staff were real professionals. The grading was super accurate and consistent, with no variation at all.

  • ★★★★★★

    They always got back to me really quickly whenever I had any questions, and I really appreciated that.
