At Markus tecno logics we have always sought to give  the attention that the client deserves, fulfilling what we promise, with a professional service and good attention. For this reason, our list of clients has grown, based on word of mouth. And the same clients come back to us, to update their equipment, or for new services that we offer. Some comments from our clients:


I agree with David. Guy has installed satellite television, surveillance cameras, gps, for more than 20 years… ..  it always does what it says it will do!

- Pattie Hogan

I highly recommend Guy Markus for photovoltaic solar panel installation. He installed panels in my house, and I am very happy with the result. Guy does what he says he's going to do, and when he says it, he does it. Many of you know that he is well known in this community for a long time, and he surely has earned this excellent reputation.

I appreciate the professional service you gave us.  The DVR works perfectly and can be viewed without any problem.

It is not easy to find a person in Mexico who consistently provides good service. We have been with Mr. Guy Markus for over 15 years and I can only think of praise for his attention.  Despite the time, Mr. Markus and his team continue to provide us with excellent personalized service without any complaints.  I highly recommend them.
