Very unprofessional and evasive. I called about replacing a patch panel in a residential property…read moreto address inconsistent internet connectivity issues. He quoted me rough pricing to replace the panel and test the cables, but when I asked a simple question about his testing capabilities (e.g. does he use certified testers or basic continuity testers, do they verify signal integrity...): first he ignored the question saying text him pictures and the address and he'll get back to me. When I asked again, he got uncomfortably evasive and told me he wouldn't tell me how he worked! Really? Delusions of grandeur - like he was protecting trade secrets. I just wanted to know if he could do any better than what I had already done in testing the cables. I told him I wouldn't hire someone without knowing what capabilities I'd be paying for, so he said "It sounds like your fishing for information" and "Take care, Buddy". Big red flags.

Technosduty did an amazing job with fixing my laptop! My laptop has been broken for 5+ months and I…read moredecided to give Technosduty a call. They were quick to respond to my request, and came in person my house at a time that worked for me. I work every day from 9am to 9pm, but they were able to work around my schedule to meet with me. When they figured out the problem, they let me know the procedure that they would take to fix my laptop. Within only a few days, my laptop was fixed! They returned my laptop to my house , and explained to me everything that was done. The price was very fair and reasonable. I will definitely contact them again if I have any problems in the future. Contact them if you want your computers fixed fast, conveniently, and at a reasonable price!

I purchased a fairly sophisticated alarm system from Mitchell over two years ago. I initially…read morereached out to him because I wanted more than the "2 doors and 1 motion detector" intro package offered by the national chains. Mitchell came to my home and we spent hours designing a system including not only all of the typical stuff such as door and window sensors and motion detectors, but also glass break monitors and water alarms for the laundry room and sump pump areas. Mitchell did not "sell" any of this stuff to me. I asked for it and we designed an excellent system together. The reason that I am writing the review today is because this is the first time that I have spoken to Mitchell in over two years. I received an alert on my control pad that a battery was low and I didn't know which device needed the new battery. I called Mitchell on his cell phone. He picked up on the second ring. I had the battery in a drawer and he identified the device and walked me through the battery change over the phone. This tells you a couple of things: 1. The equipment that Mitchell sold to me over 2 years ago works without issue. I literally have had not spoken to him in over 2 years because I have NEVER had a problem. My big problem today was that I needed a new battery. I'm OK with that. 2. Mitchell answers his phone. He is extremely responsive and knowledgeable. Mitchell is a good guy. He knows what he is doing and he sells good stuff. I recommend him without hesitation.

I had a security camera system installed by Michell over 10 years ago and I recently started having…read moreissues with the recording and playback. He suggested we troubleshoot over the phone before sending a technician to my house. Since the equipment is old, he had to send a technician after all. While I was waiting for the technician to arrive, I fiddled with the settings and ended up resolving the issue on my own. What really stood out to me was the honesty--both Mitchell and the technician could have easily said I needed new equipment or upgrade or unnecessary work, but instead they were supportive and completely upfront. Very fair, trustworthy, and refreshing to deal with a company that operates with integrity. Highly recommend for your security needs!
