The upper part of the 2 telescopic rods remained in my hands from the 1st use. The mounting system of the top part that slides in the lower part with a simple plastic clamping ring pulls in the lower section when pulling on the 2 sliding rods (above). This plastic clamping ring is simply fitted onto the fixed part and is not glued or screwed or crimped. Result = unusable without tinkering to screw the two parts together and therefore end the "telescopic" system! Unbelievable that we could sell this stuff poorly designed and that users find the good.
