      UI/UX Design Review from Neeraj Mishra

      The dashboard Perimattic delivered is minimal, well-structured, and very user-friendly. Small touches like the layout, flow, and clarity of controls make a big difference. Great work by Gaurav and his team.

      My office network crashed on Friday. VQIS was there the same day to diagnose the problem. They got it up and running the same day, and recommended a couple upgrades to insure it would not continue happening. They were out the following Monday to repair/replace the equipment. A+ for these guys, all of them know what they are doing and they had me up and running within hours of the initial phone call. THANK YOU VQIS!

      Top notch all the way! Professional yet personable. Extremely good at what they do (Mac or PC) and they explain everything in a way I can understand. VQIS does remote monthly maintenance on my work laptop (windows), as well as takes care of my family’s non-work iMacs when we have issues. I trust them so much that I’m willing to drive an hour and a half to bring them my computers if they need to fix hardware issues. Fast turn around with status updates along the way. All with a friendly attitude and a great sense of humor, which is always a plus!
