It is normal that the Model U-212s's handle spins freely when the telescope is retracted. When the telescope is extended, the handle and the rod are blocked from spinning but one can overcome the lock with mild force.
For the Model U-212s telescope's blockade to hold well, the rod has to be pulled energetically, with a snap, so its ball-bearing lock can engage fully.
Whenever your umbrella gets wet, leave it open to dry. Allow your umbrella to dry fully before folding. Otherwise mildew will form on the umbrella's fabric.
Our Unbreakable® Telescopic Umbrella is for defending against elements (in every meaning of the word) and not for clowning. It is covered in a high-quality waterproof fabric, not in abrasion proof or slash proof fabric, because it has to look, weigh, and work like a normal umbrella, so do not expect this fabric to be undamaged if you strike objects with the Unbreakable® Telescopic Umbrella.
