There are two kinds of IT people, the ones who leave you more confused than when you started, and…read morethe ones who quietly solve the problem and get you back to running your business. Working with Matt was exactly that. He was prompt, professional, and refreshingly easy to work with. No unnecessary jargon, no drama, just honest expertise and a genuine commitment to getting the job done right. As a small business owner, having someone reliable to call when technology gets in the way is invaluable. If you're looking for an IT professional who knows his craft, communicates well, and delivers on his promises, I highly recommend him. Good people are hard to find. Great IT people are even harder.

I can't say enough great things about Matt. He absolutely saved me this week…read more My Lenovo laptop completely failed to boot after a graphics driver cleanup utility corrupted the Windows boot configuration and recovery environment. The system was stuck in a recovery loop, BitLocker was triggered, and Windows wouldn't load or even reliably enter repair mode. Multiple shops I called said it would take several days just to diagnose the issue. Matt turned it around in essentially one day. He was able to manually access the system, unlock BitLocker, repair the corrupted boot configuration, rebuild the necessary Windows files, and get the machine fully operational again -- without wiping my data. That was critical, as I had local files that weren't backed up to the cloud. Beyond the technical expertise, what impressed me most was: * Clear communication * Fast turnaround * Extremely reasonable pricing * No upselling, no unnecessary "reinstall everything" approach He diagnosed the real issue quickly and fixed it correctly the first time. If you're an independent contractor who depends on your machine daily, or you run a small to mid-sized business and need reliable, competent IT support, Matt is exactly who you want on your side. Look no further. Highly, highly recommend.

This was required for me to be able to put a new band on it or I would have needed to buy a new one. I figured someone with the right tools and experience with detail may be able to help, and that's when C&K electronics came to the rescue. Perry was so nice and had the piece out in under a minute, and insisted on putting the new band on for me. I will return here for any other needs he may be able to assist me with. Thank you so much, you're the best Perry!

I had an Epson printer that needed its inkpad replaced/reset and I've tried/failed with a local HP specialist before. So when I found CMI as an authorized Epson shop as another shop (just a bit closer in terms of an audio repair I needed to run to Arlington Heights from Rogers Park), I gave them a call for an estimate. They quoted a rate that matched the competition of $89 (that was just a little farther) and offered to do the job while I waited. Since I was going to be back in the area to pickup my audio repair, I left it with them. On pickup day, I was running behind and I called them at 4:40 p.m. before closing to see whether I could still stop by. They said they'd still be open and was glad for not needing to make a separate return trip. (Will update review after I get my printer up and running again). Glad that there two great Epson repair shops in town, even if they are a haul from home.

This place and the owner, George, had excellent reviews. I called and he recognized the message, said he had the part, and said he could fix it and have me on my way in 30 minutes. Cost was $89 on a credit card. Discount for cash. Service was great. Printer producing great color photos again as well as beautiful text. I recommend George and this place highly. They are on Cortland now in Addison. Only the Epson website has the correct address. Their own website and Google and yelp all show the Fullerton address which is incorrect. Have George confirm the address when you call him to make an appointment.

I got it back and thought everything seemed fine but touch ID no longer worked, the home button made a loud sound when pressed, and the screen slightly poked out. I assumed most of this was normal and expected for not going to an Apple Store, and this was the price for getting the screen fixed at a much cheaper price. I ended up getting my screen shattered again and was gonna go back here, but he was closing soon and had no time. I went somewhere else to get it fixed. When I arrived to pick up my phone, they asked if I previously had my phone fixed by someone else, which I said yes to. They told me how my phone had several missing parts and how the touch ID not working wasn't normal. They fixed the touch ID, the screen, and the home button for no extra charge. The guy working in AdvancedTech seemed genuinely nice, and I trustworthy.Too bad my judgement was wrong.

I highly recommend this company if you have ANY computer or networking issue. The customer service is impeccable!
