Review on XXGO 2 Pcs Universal 2” Oscillating Tool Scraper Blades: Compatible with Top Brands - Bosch, Chicago, Craftsman, Dewalt, Dremel, Fein, Harbor Freight, Makita, Milwaukee, Porter Cable, Ridgid, Ryobi, Rockwell - XG1002 by Chris Horton

I used them mainly to scrape tile adhesive off the subfloor so I could lay new tiles. They worked great but I went through six (6) blades in about 25 square feet. Most of this area was cleaned by hand, so about half was done with these blades. This equates to approximately 1 blade per 2 square meters. ft. I don't know if this is "normal" or not, but it seems to me that this is not enough. Harder/better metal will likely last a lot longer. For the price, it did the job and certainly outperformed alternative removal methods.
