STICK Wireless Charger Black

I THOUGH THAT I WAS GETTING THE CORRECT BATTERY PACK FOR MY IPHONE.... IT DOES NOT WORK WITH THE SUCTION CUPS ON MY PROTECTION CASE ON MY PHONE AND IT WILL NOT STICK..... WHEN I TOOK THE PROMOTION CASE OFF IT DOES NOT FIT THE BACK OF THE IPHONE

Works well qfor me so far. Suction cups don't hold the best but work. It keeps wanting to fall off. It works question if I set my phone on top of the cups and not pick it up. I cleaned off my phone and it works and holds better. I sure do recommend this product.
