After I put this accessory to the test I was extremely pleased with its performance. It fits perfectly on my vacuum hose and makes cleaning my carpets and floors a breeze .The counterclockwise feature helps to prevent any accidental disconnections during use. Plus, it is compatible with most brands and models. The only downside is that I wish I had purchased it sooner. Overall, a great investment for any home and kitchen in need of a reliable vacuum accessory..
