They are suitable for casual use, but not suitable for use in the store. The sensors are made of plastic and are not very durable. I ended up replacing those hoses with my old snap-on head and I'm back in business. I needed new valves and for only a few dollars I bought the entire assembly and replaced the hoses and valves with my old set of gauges.
