The top-rated margarita machine on Amazon.com as of 2015 is the Margaritaville frozen concoction maker. The second most highly rated machine on Amazon.com is made by Nostalgia Electrics. The Tahiti Margaritaville frozen drink machine is also rated highly by users, according to Frontgate.
The Margaritaville frozen concoction maker can make up to 36-ounces of frozen drinks for a group or produce a small number of drinks when using the drink selector. Reviewers are fond of the shaved ice feature that involves no guesswork. The machine adds too much ice to drinks for some users, and it is hard to clean for others. Amazon.com sells several models of the Margaritaville frozen concoction maker.
Nostalgia Electrics' combination margarita and slush machine has an overall rating on Amazon of 3.5 stars, which is one star less than the top-rated Margaritaville brand. The Nostalgia Electrics machine has a 1-gallon capacity. Instead of a pitcher, it has a see-through blending chamber with a pour spout. The machine rates highly with some heavy users. Other users were dissatisfied with its ice blending and motor performance.
The Tahiti Margaritaville frozen drink machine features a blending unit with a rotating ice chute. Users can make six types of drinks that are already programmed into the machine. It also includes three drink glasses and a reservoir for catching melting ice.
