Query: Cheap, scratched glass

I purchased this tumbler set for my sister-in-law's birthday. She was very appreciative because she loved the logo & the look of the glasses. On closer inspection, the glass is very cheap & flimsy. The frosted exterior was chipped & scratched on each cup in several places. Not sure if I'd buy from this company again because the product I received was not representative of the product shown on Amazon.
