These are the only oven mitts that I personally use in my home. I have had my second pair for over 8 years. My first pair were only replaced because we took them camping and they got covered in soot from cooking over the fire. That said I have noticed a bit of wear in my second pair so I will be replacing them soon but 8 or so years is pretty good for a pair of oven mitts.
Check out my short video to see these mitts in action. You will actually get to get my old mitts in action but will do up a new video once I make myself a new pair of mitts.
