I needed a longer 1/2 inch extension cord and didn't want to pay more than $70 for a snap-off, Mac, or Matco extension cord. For what I need as a professional tech this works great. Let's face it, professional toolmakers are way too expensive these days. Mechanics don't make as much money as they spend. Professional tool brands are just STUPID expensive. The question isn't how much you can spend on tools, but how much and that's what you do with those tools!
