If grandma and weak women are the demographic for this item, then the subtly obnoxious focus in the video for this product certainly captures that message effectively. As for the rest of the population, Sodavalve is an item that is supposed to, apparently, make it easier to open a 2 liter of soda, and also helps to keep it carbonated for a longer period of time. It also appears that there may be two different products, a soda tab for carbonated water products in addition to the soda valve. For the family struggling with bedeviling bottles, $32 will get backers two of each, with an expected delivery of January 2015.
