Pressure monitoring is essential, at all time. But not all gauges are built equally, or accurately. Not all pump have safety measures. The MityVac hand pump itself, both model and the company, is proven to provide longevity (if you use it properly and not abuse it) and has multiple safety system built in. The cylinder is crazy thick and reinforced. Compare it to LA Pump and Dr Johson cylinders, one of the many companies that actually pay attention to safety over profits, the MityVac cylinders place safety over profit. As DLD mentioned many times in the past, the MityVac package broken even and even took on into the red because of the lifetime warranty.
