The crevice tool is great for cleaning out the dryer lint, in between the furniture and the wall, and extends nicely. The brush attachment gets clogged. Seems pretty useless unless you don't mind cleaning it out by hand. The mattress tool cuts down the work in half the time. The dusting tool isn't meant for heavy dusting. I feel like a slightly damp cloth does a better job. Not worth full price but worth it if you get a deal.
