The sticks are absolutely great for the price. They are smooth and bright as opposed to the 2, - parts of Kik or Tedi. Batteries are easy to insert and the pushbutton works brilliantly. The Velcro dots keep even overhead. Unfortunately, the double-sided tape is the Abkletten normally starting with. The Velcro dots on the solid surface so you should attach strong, then you can see the sticks at all times on and abkletten.
