Review: Works great! - This product works great just as intended. I find it useful when welding thin metal so I don't blow through although I have quite a few co-workers who find them useless in their specialties. I'd recommend buying this if you work with thin metal or need a somewhat accurate indicator of temperature when preheating metal. I give it 5 stars but this is a product that's usefulness is individualized. Always think before you buy but 20 dollars isn't terrible in this line of work either.
Review: Five Stars - Came broken but works as Required!
