      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!

      Galaxias Stellarum's Review Sourced from Google

      Most MSP relationships feel like being stationed on some forgotten Warhammer 40k outpost where the lights flicker, the walls sweat, the printer has become possessed by a minor daemon of spite, and every support request sounds like the opening line to a campaign nobody wants to fight. One password reset becomes trench warfare. One mailbox issue turns into a siege. One login problem starts skittering through the vents like a Genestealer with admin rights. That is the usual flavor of outsourced support: confusion, delays, mystery suffering, and a whole lot of “we’ll circle back” while the planet burns.ACORN is not that.ACORN is the battle barge that arrives when the sky is already on fire and, instead of giving speeches about process, actually starts solving the damn problem.Since ACORN became the MSP for my company, the IT team has been genuinely happier. Not “corporate smile in a meeting” happier. Not “we put that in an email because it sounds polite” happier. I mean actually happier. Less friction. Faster answers. Better support. Real help from people who seem to understand that when something breaks, the goal is to fix it before it mutates into a second, uglier problem with tentacles.And the people matter here, because the people at ACORN have been consistently excellent. Afzaal, Saad, Asher, Samhesh, Chelsea, Tywon, Mesha, Ashley, and others I have worked with have all been fantastic. They are helpful, responsive, capable, and they move with the kind of speed that makes you feel like your issue has been handed to someone who has already seen this beast before and knows exactly where to put the blade. There is a huge difference between “support technician” and “person who can actually get me out of this mess,” and the ACORN team keeps proving they are the second kind.That is what stands out most. They do not just answer. They resolve. They do not just acknowledge tickets like monks copying the Book of Mild Concern by candlelight. They get in there, make sense of the chaos, and get results. When you work in IT, you develop a sixth sense for who is going to waste your time and who is going to save your day. ACORN has consistently landed in the second category.And in the grim darkness of modern business technology, that matters more than people realize.Because every company eventually reaches that moment where a simple issue threatens to become a full battlefield. Email breaks. Access gets weird. Permissions decide to become theological. A user swears they did nothing right before unleashing an entire mechanical apocalypse. In those moments, you do not want vague reassurance. You do not want jargon wrapped in fog. You want competence. You want speed. You want someone who can look at the techno-horror crawling out of the floor panels and say, “Yeah, no, kill it with fire,” and then actually fix the issue instead of studying it like a museum exhibit.That has been my experience with ACORN.They have brought a level of consistency, urgency, and real usefulness that has made life better for the ARGUS IT team. The support feels human, the turnaround feels meaningful, and the outcomes feel solid. The people are strong, the service is strong, and the whole relationship has made a positive difference where it actually counts: in the day-to-day reality of getting problems solved without unnecessary suffering.If ACORN ever decides to put their logo on a Warhammer-style battle standard and march it across the wreckage of broken tickets and screaming copiers, I would not even question it. They have earned that energy.Highly recommended.

      Used a fraudulent tracking number to "placeholder" a shipment, the tracking number was set to re-deliver to their address. The item they claimed to have shipped was the wrong weight (4lb) when the actual item in a box is exactly 6.1lbs. When asked about the questionable tracking, they opted to refund the order instead of fixing it. As a note, they were underselling MSI Direct on a motherboard by almost $150...

      Ordered a product from them off of Amazon. They were never clear on shipping and claimed they sent to UPS but UPS says they never received. This company just wants to hold your money and when you finally call them on it they fold but if not they will hold your money as long as they can with no explanation as to why. They never reached out to me once until I called them up after I was past delivery time with not a single word.
