The world is full of cons, scams and just plain crappy products. Many of these products are designed to prey on the vulnerable and uneducated, touted by websites filled with fantastic claims and promises that don’t quite add up.

Premium bottled water, canned oxygen and glass discs that can improve the nutrition of any liquid poured over it are just a few of the products this video reviews (and insults).

Some of these products, however, are so outlandish (and often hilarious) that perhaps the most unbelievable thing about them is that anybody is stupid enough to buy them in the first place.
