I have a Craftsman band saw that uses 70 1/2 inch diameter blades. A few days ago I bought 4 new blades, 2 1/2" blades and 2 3/16" blades. When they came in the mail today (on time) I installed one of the 1/8 inch blades. The blade broke after about half an hour of use so I installed one of the 3/16 inch blades. This blade also broke after half an hour of use. Also, the paint that was on the blades got onto the wood I was cutting. The blades also made a clicking sound (from the point they were brought together) when I cut my pieces. I used to order replacement blades from Craftsman/Sears and NEVER HAD THOSE PROBLEMS! Every blade I've bought from Sears has lasted almost a full season! Of course I want my money back for useless Powertech blades!
