Our experience with Keener Security was above and beyond exceptional. We had Alex come in and give us a quote and explain in detail what was available and compared it to our wish list. We made some adjustments and within a few days, Alex was back with an Assistant and did the installation. Alex's tutoring was excellent with explanations, pros and cons to all of our questions and concerns. We can not emphasize our appreciation for all that Alex and Keener Security have done for us. We had questions days after the installation and never had a problem getting answers immediately. It did not matter when we called. If there is a 5-star rating, Alex and Keener Security deserve 6. Thank you very much.
