Review on 🔴 Enhance Safety with Rutland Products 701-6 Magnetic Burn Indicator, Red by Jennifer Duncan

It took our wood stove about a year before the spring on the back fell out of the channel connecting it to the indicator needle on the front. I suspect if you used this vertically on a single wall stovepipe it would last a lot longer. We had it lying horizontally on the stove because we have a double-walled pipe. Eventually all the back and forth movement combined with gravity caused the feather to fall out. However, I ordered the same model again. It's pretty cheap and good enough.
