I bought this to use with my Dyson V7 and didn't want to pay extra for a Dyson adapter as some other brands have suggested. This is perfect for avoiding loss of suction and was a lot easier than lugging my stand around. I've used it to clean my car, small trash cans on my desk, and "dust" shelves. There are no deadlocks yet, but I can see how it will eventually happen. Seems like an easy way to clear blockages is with an unrolled paperclip or something.
