“Mandle, and his team at Control FREQ, are hands down, the most capable, most skilled, and best at delivering desired results of ANY organization I have ever used! Since using Mandle close to 15 years ago, and having gone through many major changes in our audio/video systems, inside and outside of our home…I have not used anyone else! He and his team make it easy…they speak ‘English’ to the ‘less informed’ and deliver exactly what we want without any of the brain damage that usually comes with new systems! They can be trusted with large and small jobs and they consistently deliver on their promises! Quite simply…they are the very best out there! I cannot recommend them more highly!”

He provides personal touch to all his endeavors including one on one tutorials, if needed, for new tech equipment and tech support. He is skilled in all types of equipment, but most especially, Apple products. His tech support has been consistently reliable, and we are not the least bit reluctant to recommend him and his company, Control FREQ.”
