Good idea but lacks functionality. It doesn't snap; it just flops - with very little pressure. If you want to use it to clean the surface of dust, you literally have to hold the nozzle in the position where you want to clean. The price would be great if the product actually worked as intended. But since this is absolutely not the case, there is no amount of money that is small enough to make a good deal out of it. This is a waste of time and money. I would return it but I waited too long to start spring cleaning to know how badly it would work.
