I have an old DC44 laptop so it is difficult to find jets. I really needed a flexible hose so the jets were a bonus. When the hose is attached to the DC44, it wiggles and wobbles a bit, but doesn't seem to affect suction. The problem is that the nozzles are too narrow to fit in the hose, including the ones that come with the kit! ridiculous. I could understand if these were my own original nozzles, but shipping products that don't even fit in the box is a quality control issue. I finally managed to flatten the entire shank of the crevice tool to pull enough of it down the hose to use for what I need, so I'm keeping it to myself.
