    1.0 Patrice H. Chicago, IL

    I will not recommend this unprofessional bitch MARCO hes a f******* scammer! This b**** switch the code to my alarm system the day I cancel he is b**** a** scum of the f******* earth. He charges your account twice a month so if you get this service make sure you pay attention to him charging you account. He a f******* dirt bag who tell customer they have to they account connected so he can charge it without your authorization. This motherf***** is not fit to handle real customers and I will highly go to a more legitimate company like ADT, BRINKS the real company not his contract a** LLC.

    Response from Company:

    . I'd like to reply to this Ridiculous Post here bye Patrice Hamlin. She has been our client since 2015 9 Long years during that time Patrice has had money issues as do we all and she was one of our leading customers Always calling in to move her dates around for payment, methods she pays late payment etc. Out of the kindness of my heart I tried my best to help her as we were protecting her home and family. We never raised any rates on her , she never paid for 1 service call or any replacement equipment. Sometime last fall we needed to upgrade her cell and keypad and some window sensors and 2 key fobs for free again!! She told me was closing down her acct for payment and wanted to pay with pre paid credit cards which we do not accept. I told her let me know what she wanted to do or w would need to part ways I have Never charged her accts twice it was hard enough to get paid. She then canceled I thanked her for her business for all the years. I told her i would send here a pre paid package to return our equipment we just installed. She refused texted to go F myself and said she put it the garbage F U was sent to my cell outside of that she has sent me 10 plus nasty mouth messages. I responded that she has 30 days to return the equipment she said she put in the garbage or she will be sent to collections. Once she received the collection letter my text on my phone blew up with that nasty mouth again. I did not respond again. If she was so angry and hated my company and the way i treated her WHY would she stay for 9 years?? I guess when the Free stuff stops and the hand outs end this is how she responded to me this way. . Since this post she is in collections for over $700 and a Defamation suit has started I m sorry to my clients that read this post i have learned my lesson moving forward - Marco Sarli

    5.0 Peter S. Wilmette, IL

    Marco helped guide us through the process and made excellent recommendations along the way. Very professional, knowledgeable and responsive when we had questions. Highly recommend Marco and his team.

    Did show up

    5.0 Sanford P. Geneva, IL

    All processes are coordinated by the owner ( Marco). He is responsive, professional, expert in his field, transparent, has competitive pricing, uses the most advanced systems, and customer oriented. Marco personally makes sure all aspects of the security system (sensors/cameras/monitoring/applications) are working seamlessly before project completion. He was a pleasure to work with and his associates were top notch.

    4.5 Tino V. Berwyn, IL

    Marco & Bill were excellent installing and knowledgeable about their products. Install four cameras in one day and were very tidy and picked up after themselves I would recommend them to anyone very happy with the work.

    5.0 John K. Crystal Lake, IL

    Marco was professional, knowledgeable, experienced, and seemed to be genuinely interested in protecting us and our home. I liked the fact that this is his own business and not just a job for him. This is his thing and he is proud of it. Glad we found him.

    5.0 Hope D. New Lenox Il, IL

    Marco is very knowledgeable and professional about the services and products he sells and installs. Has an amazing work ethic. Did install in a very timly manner. Would definitely recommend his services.

    4.5 Kurt S. Oakbrook Terrace, IL

    Marco always following through with what he said. I appreciated his urgency about getting the job done.

    4.5 Jayme D. Tinley Park, IL

    contractor was knowledgeable, reliable and responded to all our questions. My only complaint is we can not utilize the HD camera resolution due to our WIFI capabilities even after installing an ORBI WIFI booster. This is something I would still like resolved.

    4.0 Sean C. Sugar Grove, IL

    Really good guy to work with.

    Seal of Approval

    What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.
    2. Verify Insurance
      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
    3. Verification of State Business Filings
      For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
    4. Criminal Records Search
      HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
    5. Sex Offender Search
      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
    6. Bankruptcy Search
      We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
    7. Legal Search for Civil Judgments
      We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
    8. Liens Search
      We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
