Review on TDVS Universal Vacuum Hose Adapter Kit: Enhance Compatibility with Versatile Reducer Attachment Set - Unmatched Fit for Various Vacuums & Attachments - 1 1/16 to 1 3/4 Inches - 4 Pieces by Jeanette Green

Bought these adapters to use my Dyson V6 accessories on my Shark Vertex Ultralight. The Shark came with a few accessories but I still wanted to use the Dyson accessories as I have 7 to choose from. NONE of these adapters worked. Some will fit on one end but not the other end. Some didn't fit at all! A couple of combinations I tried didn't work either. The Rubik's Cube would not solve. Sent back the same day I received it. As for the physical quality of the actual adapters, they were decent quality plastic. They didn't seem too skinny or flimsy. There were no rough edges or sharp edges.
