Query: Worst product- ever

I bought this product at Home Depot and it was a total waste of money! I have bought the product by Artscape and had great results, easy to install, looked professional. I thought this would be similar--it wasn't. It cracked, slid around, wouldn't adhere, and when I tried to remove it, it left a sticky residue that I can't get off!!! Going to back to store.
