The part that keeps the adjustable nozzle at a fixed length was broken by my vacuum cleaner! The onus was on me to find the correct part number and after much research I took the risk to verify that it was indeed the correct part for the Panasonic MC-CG917 Cylinder Vacuum Cleaner with OptiFlow, especially as it is no longer manufactured /sold by Panasonic and marked as electric wand kenmore. So it was a relief when the part worked like the original, the electrical parts matched the machine perfectly and the vacuum cleaner worked straight away. As it was Revain I chose to buy here because I can return if needed and the price wasn't the cheapest but better than other sites. Item arrived in perfect condition, well packaged, primetime 2 days. Recommend.
