The first blade lasted a week before becoming dull and unable to cut without burning. The second blade lasted almost three weeks before breaking. All I use the band saw for is 90% wood saws and 10% acrylic saws. It is used for cutting blanks on a lathe for making handles. The original blade lasted several months until I tried cutting acrylic that wasn't fully cured. So I assumed them to last at least 6 months instead of a few weeks. I do not recommend this.
