Ya never know about them tumblers. Ive got a old lyman that I bought in 1988 and its still going strong. I bought a bigger tumbler probably back in 2000 and it didnt last but 4 years. My buddy has gone through at least 5 tumblers in the last 10 or 15 years. Some last some dont. I keep mine out in the garage just in case it did catch fire. I wouldnt recommend ever keeping one in the house.
