Review on Tefuawe Auto Darkening Welding Lens with True Color Blue Technology, Shade 10, 2x4.25 + 2 Replacement Outside Cover Lens for Pipeliner Welding Hood by Chris Cruz

The view through this lens is as clear as most famous lenses and there is no discoloration or staining on the lens. The sensitivity is quite high, so I had no problems with flashing. I even looked through the gap while my buddy was digging and it was dark for me. I am very impressed with the quality of this lens for the price. I've been using it for a little over a month, time will tell how long it lasts.
