I find this invention great to finally have nothing sticking to the disc. The holder fits perfectly into the CD slot and holds. Also CDs can be played back if you want. My Samsung S5 has held the first days in the holder. First, it opened at the slightest movement, and cell phone kept falling out while driving. Mitlerweile it no longer closes and locks no longer a case of the size of my cell phone. A smaller cell phone was still going. But does not help me.
