I truly feared all of my files were gone forever. Wedding pictures, baby photos, and vacations we'd taken over the years. Plus all my music and video files. Adam and the Nerd Rangers saved almost everything for me on a 5TB drive. Their pricing is incredibly reasonable. I'd called a couple services that would have needed me to mail off the drive and they quoted me much higher rates as their minimums. I'm so glad I found Nerd Rangers. They're local and kept me updated every step of the way. I can't recommend them enough. Thanks again guys!

I was unsuccessful with a previous computer store, located on Ogden ave, figuring out the reason my…read morehigh end gaming PC would crash while running games. They ran their tests, charged me a fee and could not replicate the failure. Once I got the computer home, it crashed once the game was being played and they said they did everything they could and I was out of luck. I decided months later to see Adam at nerd rangers. He was very thorough in gaining background on the issue. He asked me whether the other repair shop tried to run the actual game? I was not sure so he went ahead and loaded Fortnite and said he would do his best to replicate the issue. Later that day he reached out to let me know that he believes he found the reason the game crashed (as it did for him) and he felt confident that he fixed the issue. When I went to pick up the computer he reassured me that if for some reason the fix didn't work he would continue to work with me to identify the problem. Happy to report that I've run multiple games with zero crashes and everything is running fine. The level of service, detailed questions and customer care was excellent. Thanks Adam!

They didn't work and I spent HOURS driving back and forth to have them try again, and ultimately to return them), Mark made copies of the key quickly and they worked! and when we needed some springs in our lock fixed, Mark was responsive! He told me he would arrive in about an hour, and about ten minutes out gave me a courtesy call to let me know he was close by. He not only fixed the lock, he also tightened up the screws and the screen door (that would slam shut previously). Mark was courteous, kind, professional and knowledgeable throughout the whole experience. Definitely going with Mark again anytime we have any key/lock needs! Thank you!

I reached out and Don came by the next morning, and gave me a quick and simple quote that blew the other guys out of the water. He was quick and professional, and fully delivered with terrific quality cameras. We have had two small issues since then (not to do with the quality of work, just minor snafus) and Don responded to me right away and helped me fix the problem. These guys will be my first call the next time I need anything like this.

When we checked into ADT and Comcast to find out what their pricing was, we were taken back. They try to sell you on low cost installation, but lock you into a two-year service agreement at high costs. We looked into local Video/Security experts and were lucky to find Jim who runs spyallday, Inc. Jim has over 20 years in law enforcement in the western suburbs and is an expert in Video surveillance. We were able to get top of the line Cameras/installation with NO monthly fees . Significantly less than ADT or Comcast. We can now check on the kids with our smart phones anytime and from anywhere!

I was…read moreapprehensive as I'm not a regular client at shooting ranges but was considering becoming one, and I wanted to know more about the carry/conceal aspects of owning a firearm in Illinois. The classes are priced competitively, take 16 hours which included qualifying time at a local range, and had ten people attending. Much of the classroom material consists of the Illinois State Police worded laws and restrictions, but the instructor Jason took the time to explain anything that wasn't clear. Being in law enforcement, Jason also shared plenty of practical experience and videos of real-life situations. If you are considering a conceal & carry class I recommend Glenbard Security.
