Question: Would this be good to make slushies for children as well?  What kind of syrup woudl you buy?
Document: Works perfect for slushies of all flavors! We just really enjoy using a frozen can of any juice and it makes great summer treats. You can make enough for 6 kids!
My father has been looking for years for a way to make good homemade frozen coffee drinks. We finally went all out and got him the Margaritaville Frozen concoction maker which he loves.
I haven't had my Margaritaville long, but so far I am loving it. I have a nice, evenly mixed drink at a touch of a button. So easy and so good! It does take up some room on my countertops, but well worth it! :-)
When this first came out a few years ago, I had a part-time job in the Housewares department of a large retail store. And I thought it was kind of ridiculous, to be honest! But once I started looking into them and saw how much people seem to like them, I decided I needed to buy one, and I have changed my mind!
Bought two; one as a gift and another for our use. Both are performing perfectly. Pretty good sized unit so make sure you have a spot picked out to store/display. Also do some web searching to find all those great drink/concoction recipes out there. We are still experimenting with different mixtures and ingredients in search of our most favorite concoction and I must say it continues to be a very enjoyable journey :)!
I am happy with my Margarittaville DM600, it makes great margaritta's. The adjustable serving size on the bigger models would be nice but I couldn't justify the added price for that feature. It is a tall unit that won't fit inside most cabinets. It is a sturdy, well designed machine and cleans up without to much difficulty. At the end of the night on last use, I dropped the pitcher and mixer in a sink with hot soapy water and then just needed to be rinsed and dried the next day.
I have used this product everyday since I received it a few weeks ago. You can make snowcones with the shaved ice some awesome pi&ntilde;a coladas and much more. No more going to sonic just pour your favorite flavors in the pitcher and ice in the top and start blending. This product is a little pricey but well worth it.
I bought this mixer for my 50th birthday party. The machine worked beautifully and was so easy to use. It made 4 servings of the margarita cups and every serving was so good. This mixer produces great tasty margarita's and the consistancy is A+. It definitely made my party lively, so glad I got this as it went well with my Cinco de Mayo theme fajitas & margaritas. Also easy instructions on how to use and care for the mixer and very easy to clean.
Bought this for our new house and yes it makes a great margarita but also just great for making slushies for the kids
Great we love this , best product , lots of fun ,  several people commented that they were going to buy this also.
