Great product use daily in a semi truck shop. Only issue is it not being a high flow style, making airing up tires a little slow. Note I do only use this when checking tire pressure and toping of tires for drivers. Of course I have also swapped the end to have a clip on nozzle for valve stems. I've had mine for about 6 months I believe at this point , and it has held up perfectly mine is dirty for oil and grease but has no issues. It is a great tool, and priced well. Would work perfect for car tires or a quick check of pressure on semi tires. Helps eliminate the need to switch between a gauge and air Chuck.
