I bought for ~ 6000. while in most stores it was for 11,000. It was sold cheaply, apparently due to the rare size of the tape. With difficulty I later found the remnants in one store of the Praktika tape. Original Makita tapes are very expensive. But, probably, you can cut off a 100x610 tape from the edge (I haven’t tried it myself). Sanded a concrete wall from cement blunders. There wasn't much dust. The dust collector works well. Particularly pleased with the auto-centering of the tape. It is not necessary to constantly adjust the position of the tape so that it does not slip to the side during work. Would have given it a 5 if it weren't for the rare size of the tape.
