M31 Inc

Very well. Quick, professional, knowledgeable, friendly.

Topp Robertson really knows his technology and does quality work. I have called him a couple of times when the HD Tv channels (only the ones with weak signals) stopped working. Topp described what to look for, found the cause and corrected myself.

M31 did exactly what was asked of them at a fair price. Owner was helpful, knowledgeable, and helped quickly diagnosis one bad component. Would recommend M31 to others.

Provided advice on the phone for installing my own antenna and did not charge me anything. Very helpful and considerate!

Excellent and thorough

Made appointment on-time, explained what he thought was needed and why. Then completed agreed upon work and cleaned up. Great guy, professional and made sure all was working to my satisfaction. Told me to call if something not to satisfaction later. Reasonable pricing. Antenna working great. I cut out overpriced TV cable and getting along great.

Topp did a great job. He is an expert in audio video and gets right to the problem.

It was an exceptional experience for me. Topp arrived at the promised time and completed the work in the time frame he promised.  He was very professional in his approach and the quality of his efforts were evident in the improvement of the video quality of the plasma TV. He was very open to my many questions as he worked each step in the process and answered them with clear explanations that I could understand. The documents he emailed detailing the history of the calibration changes and settings arrived a couple of days after the work was completed. I was exceptionally pleased with his demeanor and the results of his work.

Topp is extremely knowledgable, professional and pleasant guy to work with.  When I first contacted him to explain our needs, he gave several options/scenarios about how different things might work.  I followed up with him to schedule an appointment and he actually called me back when he was recovering from minor surgery in the hospital?that's amazing service & dedication!  The day of the appointment was when DFW had extreme weather/storms but he came anyway and even helped identify a leak in our attic!  He gave us a lot of information and options to consider and was very honest.  He did not charge me to come out and check to see what our best options would be but I would have been willing to pay for his time & will hire in future.

He arrived on time with equipment. He was very knowledgeable and professional. He had some trouble calibrating one of our TVs (we have 3)  but was able to repair the wall outlet. He was pleasant and gave good advice. We thought his service was a bargain. I have already recommended him to two other people.

Excellent service -- competent, courteous, exactly as promised. Took time to explain in detail how to use new system. Would highly recommend.

Topp is the best service provider I have ever used.
I cancelled cable and needed a HD Antenna installed, and called Topp after reading reviews for him.  He was prompt, informative, and very comfortable to work with.  He did a fabulous job considering I had a fairly unique setup.
But here is what sets him apart:  There was an antenna in my attic, but I just assumed it was the old kind and obsolete.  I mentioned the antenna to Topp when I showed him to the attic, and he told me that was the very antenna he had brought to install and offered to use it to save me about $60!!  How many providers would be so honest?  I would have never known.  He was also open to using any other supplies I had on hand to save me a few bucks.  
I think that about says it all - I wish every provider, were as honest and easy to work with as Topp!!

Topp deserves an A+  We don't have cable or satellite TV and had a real problem being able to tune in all the HD local channels.  It was very frustrating watching TV when the picture would freeze, pixilate, or disappear all together. Topp made 2 trips with very sophisticated equipment to make adjustments. He was able to find the "sweet spot" on the roof for our antenna & point it in just the right direction. Now evening TV watching is enjoyable

It went very well. Topp explained what might be involved and gave a few options. He is very tech savvy and knows what it takes to make this type of connection work. His pricing is up front and inline with industrial pricing.  He was prompt and helped my mother set up her channel selection. Everything is working great.

Excellent service. From my initial phone call, all the way through completion of the installation. I would definitely hire again.

Topp was wonderful to work with. I had moved into a new house and had bought a LG 55" TV to mount on my wall. I did all the work myself, but had called Topp for some information on calibrating the TV in the environment I had put it in. He came and did a bang up job on it, and even did a quick "tune up" on my older model big screen that was relegated to a different room.
Topp exudes knowledge of his field and you can tell he absolutely loves what he does. I would recommend him to anyone and would use him again in a heartbeat!

Read referrals from Angie list and called Topp at M31 Inc.
He advised installing an attic antennae that would perform equally well to the roof antennae.
He had equipment to measure the best direction as well as the least decibal signal loss location in the attic.
Installed and custom trimmed it in the attic and got every station perfectly.
Reasonably priced, would definitely use him again.

Topp was very courteous and extremely knowledgeable.  His professionalism and expertise made me feel confident that I had called
the right company ~ one I could trust.  His choice for the antenna I needed was based on service, not profit.  He took time to explain how everything would operate and that the way he installed it would provide long-term, great service.  I genuinely appreciate companies who have your best interest in mind.  This company delivered above and beyond my expectations ~ from my first call ~ all the way through installation.

Topp called ahead to confirm arrival time and, upon arrival, he worked diligently to install,set-up and correct all items requested. He performed in a professional, thorough, and courteous manner. Working with him was a very positive experience and we are pleased with the work he performed.

Topp was very knowledgeable about what would work to meet my objectives.  He was on time for the appointment and worked quickly and efficiently to locate the best location for the antenna and to install it.  I was really pleased with the service and would highly recommend him.

We have used Topp for over 10-years - he is always 2 steps ahead of the ever changing technology.   He has pulled all the wiring for our internal sound system throughout the whole house, installed every TV, DVD, and programmed the universal remotes.  He also reviewed and recommended the equipment for our sound system and hooked everything up.    I could go on and on.   
We have referred him to countless friends and have always had great feedback.   On top at being good at what he does Topp is super clean and very respectful of your home.   At the end of every job he cleans ever speck of dust of debris he may have created.
The best thing is that you are going to get the owner of the company every time.   
I would highly recommend him!
