Update: The seller quickly contacted me after I left a review below. They offered to send replacements and expedite delivery. The new bracelet arrived in better condition than the first. Now I have a good blade on my saw. Upgrading the rating for customer service. I'm still not sure about the general quality control but for now I'm happy with the result. First Review: Let me start by saying that I know how to use a band saw. I took it out of the box very carefully and unfolded it. Also, place it in the saw very carefully. The reviews for this blade are pretty good, but if you look at other blades from this manufacturer you will see some comments about blades arriving with severe warping/twisting. Usually next to a weld, like mine. Poor quality control makes it a matter of chance and puts me on the losers list. This makes the blade unusable. I hate to give 1 star but there is no other rating for a product that arrives unusable. Since it is unsuitable for use out of the box, I cannot yet say anything about the reduction in performance or duration. I cut the package and now it's too much trouble to send it back. I thought I would save a few bucks but I just ran out of money. I will be buying some more blades locally again where I can return them if they run into problems.
