You didn't say that on your website. The product I ordered is described as fitting Shark. It doesn't say anything about also buying a ridiculously priced 19.99 piece of plastic to make it work. I want a full refund for this product.
For shark we have the special combo which includes the tool and an adapter: https://www.ezvacuum.com/shark-under-appliance-attachment-tool-wand-adaptor.html
Since you already have the tool, please get the adapter here at https://www.ezvacuum.com/fit-all-vacuum-cleaner-attachment-adpater-35mm-to-1-1-4.html
