Review on Think Crucial Vacuum Hose Parts - Replacement for Shark Hose Handle Part 153FFJ - Fits NV355, NV356, NV357, NV356e NV370 - Light, Durable Design for Purified, Healthier Air - (1 Pack) by Raye Johnson

Everything seems to be done well. I can't securely "snap" the handle onto the vertical metal bar. This seems to loosen the suction and when I try to pull the vacuum back while vacuuming the handle pops out. This keeps the pen in my hand and the vacuum cleaner on the floor. Upon further investigation, I see that the red button clip does not protrude far enough to securely engage the groove on the vacuum frame. This will loosen the grip.
