This item did not fit my Dyson V7 in spite of the fact that the information indicated it would. I initiated a return, but then learned it would cost $50 to $60 to return it to China address in China. The return address was not available until I initiated the return. The item cost $25.99 so I will not return it, but will not support this vendor, and hope your other customers are more cautious than I was.
Please consider requiring vendors to disclose all information about returned items.
