This replacement hardened shade 8 is just what I needed for my automotive welding projects. According to my experience, IT`S durable and very easy to install onto my welding helmet. The shade is perfect for protecting my eyes while allowing me to have a clear view of the work I'm doing. The only con I have is that it doesn't come with any instructions but I was able to figure out how to install it myself .Overall, I highly recommend this shade for anyone in the automotive welding industry..
