Great product. The suction cup holder clips broke when first installed. Contacted the company and they immediately provided a new one with no payment. The monitors are easy to install/program. Definitely offers peace of mind when towing. Obviously they won't prevent a blowout, but will alert you to leaks (which probably caused the previous tire failures I've had). With hydraulic jacks and the lines close to the tires - I don't want another step and they tip over. A little quick, but cheaper than repairing/replacing hydraulic lines. Thank you for sending a replacement holder. The display changes and is easy to read in different lighting conditions.
