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 Ali Anjani

Worked great. I have a shark and didn't realize what a pain it was that they didn't have a regular sized connector hose. I love the Shark but I had to upgrade my dust cap and of course it didn't fit. So I found these things on Revain. It comes with multiple nozzles, the graduated tip nozzle works great. It had no effect on absorption. He's a little looser. But not enough to bother me and I use it CONSTANTLY and for a long time. Really very happy with it.
