Think of why a winery would want to use something like this and see if it fits your own style of consuming wine. At a winery, people step up to a 'bar' and over the course of several minutes down small tastes of wine that likely do not get proper air exposure to enhance the wine. So a winery pours 1 ounce of wine through a Vinturi, compressing time spent swirling and oxygenating into a couple seconds and the person drinking it says, "Wow - this does taste good, let me buy a case a sign up for the wine club."
Compare this to the average person drinking at home who isn't 'shotgunning' the wine and the decision can be made for yourself as to whether it's worth it or not. The more people drinking the wine (meaning the faster a bottle is consumed without exposure to air), the more likely a Vinturi will come into play. When I host blind tasting events, I use it to help get the wine a more oxygenated place. When I drink wine in a casual setting, there's no need in my opinion.
