Review on 6 PCS Mixed Wood Oscillating Tool Blades Set for Fein Multimaster, Porter Rockwell Cable, Black & Decker, Ridgid Ryobi, Dewalt, Chicago - Quick Release Saw Blades for Multitool Efficiency by Adam Allard

Attention! These blades will not work with Bosch multi-tools and will damage the tool if used. Note that the manufacturer claims they will work, but don't believe it. You need a star mount blade. To make matters worse, the seller doesn't allow returns so they know it won't work and just misled you as an uninformed buyer. This is a scam and Revain should do something about the misleading ads. Sorry I bought them and now have to throw them away while the seller laughs at your misleading ad. Tragedy! gary
