I burn through band saw blades pretty quickly in the production shop they use to cut resin rods. They don't last very long but I wasn't expecting much for the price. To be honest I can wear out a "good" blade pretty quickly. The first few blades tracked well and worked great until I wore the blade down. The last two I received had creases from the packaging and obviously didn't go straight into the saw. I can live with that for my purposes, but if you're doing a re-edit or anything that needs to be direct I'd look elsewhere until they sort out that quality control.
