It is regrettable that you did not ask for support so you actually could have done it right the first time. Buying a product without any knowledge of how to install it and blaming the product is not a honest review. The product you ordered @ 37 7/8 is our FLOORing product. As such, yes it is difficult to install on walls and takes more labor than the wall product.
Hate you were so frustrated, but it was easily solved by asking an experienced installer rather than being a chuck in a truck. Starting with a basic understanding of how to install drywall helps with installing our or any mass loaded barrier.
