Blenders for frozen drinks are blenders that are good for making slushies, frozen alcoholic drinks and frozen coffee beverages. Ice crushing is a crucial capability for a good frozen drink blender.
Countertop and professional-grade models are rated highest for this purpose, while small, single-serve blenders tend to rate low. Unsurprisingly, many of the users' favorites in this category are designed specifically for this use, such as the various Margaritaville models.
The leading brands in this category are Margaritaville and oster; the former is slightly pricey (but very popular nonetheless), while the latter is a more affordable brand, with most of their blenders priced under $100.
