I purchased this set for essentially the purposes listed in the product description. For all of those purposes these attachments work very well. In addition, the crevice tool works very well cleaning up those hard to reach spots on your couches. I'm definitely impressed. The only thing that requires a bit more effort is when the crevice tool is used to clean the lint trap grate on a front load dryer. When the tool is extended to curve down in that slot, then it can retract back fairly easily when you push down on it. All you have to do is hold it at the base of where it extends, and then it does the cleaning job famously. Overall, very good products- expecially since they are so specialized.
