im the one thats been advocating them so thought id advise . the ones at wallys world and some of the other new ones dont hold up like they did when i started using them . my first was used and made in china. but it lasted until i tore it up removing a cross threaded bolt . over a yr. this new one looks like a duck but it anit the the same duck. its working but i get a feelin they made it with an automatic time destruct built in.sounds worse every day.just thought id advise.
