Beware of poorly made wands. I have ordered 2 and had to send them both back for different reasons. I'm not sure who's making them, but they are clearly inferior even though selling at top dollar. The "early" telescopic wand had visible wiring in its center which obviously obstructed the flow of lint, fiber, hair, dirt, etc. Miele no longer makes them, but I was sent one without knowing about it. The second wand had a defective latch and would not stay extended. This was only after 3 uses. In both cases, the seller has been extremely cooperative, thankfully!
