Review: Rachaell decided to put the Winesulator™ to the test on a scorching hot day. Leaving it outside for two hours, she measured the temperature of the iced water before and after, only to find that it didn't work. While this may be disappointing, it's important to note that individual experiences may vary. The Winesulator™ in Matte Black color by BrüMate is designed to keep your wine chilled for hours, making it perfect for outdoor gatherings or picnics. Its sleek matte black color adds a touch of elegance to any occasion. However, it's worth considering that extreme temperatures may affect its performance. Overall, the Winesulator™ offers a stylish and convenient solution for keeping your wine cool, but it's important to manage your expectations in extreme weather conditions.
