Some time back I put out an inquiry to see if there was an American made tire gauge, I was led to believe these were and purchased two. However they are made in China and carry a 5 year warranty including the battery. Mine failed within 6 months so I fired off an angry complaint to Measurement LTD, Inc. the manufacturer. I received a very quick response with a promise to replace the defective gauge plus a supply of batteries. I received them quickly and a new battery fixed the dead gauge. While I would like to buy American I guess that's impossible but at least they did stand behind their product.
