IKEA Bekant White Standing Desk

I used the table for ~1-2 years. We accommodate pickups on 8/17 between 12-4pm. This is a height-adjustable standing desk, but the height adjustment function is slightly unstable when you lower the table by too much. The table is stable at any height, but when you try to lower it too much or raise it too high, I think the device that’s supposed to stop it at those limits might have come off. Because of that, it keeps going down or up without stopping, and once the leg even came off. Everything else is fine, but that makes it unstable. I am selling it at a big discount compared to the original price of ~$350!
