The devices are big and bulky like the were created in the early 1900s. They drain your battery all year long, so you must put alternative devices to ensure battery stays charged or make sure you drive daily. Customer service is not up to par let alone just reaching someone. On top of all that, the devices are faulty. There is always an issue with the devices not working or not being able to start the car because of the device. This could be due bad wiring, bad devices, lack of communication between the devices, etc. These devices cause more harm on your car than regular wear and tear. They issue false positives tests, so be careful what you eat or drink before blowing in the device. Did I mention the ridiculous lockout fees they refuse to reverse most of the time? They charge about $100+ monthly to use on top of the bi-monthly calibrations you must get to keep you device working semi-properly. Which use to cost around $15-$20, now cost $40-$100 depending on where you go. There is no cap on what shops can charge you for calibrations, removals or installs. Some shops are charging up $500+ for removals and installs. This company is a rip off and so is the state that allows them to operate. The need to be stopped and lawsuits need to be set in place immediately.
