Whether the Viking 15" Undercounter/Freestanding Nugget Ice Machine FGNI515 is worth purchasing for home use depends on your specific needs and preferences. If you enjoy having a constant supply of nugget ice, which is chewable and great for drinks and cocktails, and if you entertain frequently or have a large family, this ice machine could be a valuable addition to your home. However, it's essential to consider factors such as space availability, budget, and your actual ice consumption. The machine's upfront cost and ongoing maintenance should also be considered. If nugget ice is a must-have for you, and you can justify the investment, the Viking FGNI515 can be an excellent appliance to enhance your home's convenience and entertainment capabilities.
