Amazing Slush Machine

I have been pondering getting one of these machines for a while but what did it for me was the XL size machine. It works amazing! Slushes pretty much any thing with minimal effort. Have had no problems at all. Clean up is a breeze. Keeps going if you add cold ingredients. LOVE IT!

Ninja 150

How great!! Small "batch" makes enuf for 2 or 3 large slurpees /Bellini's in about 9 minutes! Quieter than I thought it would be,too. Needs a fair bit of counter space as it's a kinda large machine, but SO worth it! My only wish is that the lid for the pour had hinges. Easy to clean and operate, this Ninja is for Everyone :-)

Fun but little loud

We have been using the SLUSHI none stop and my only complaint is the sound it is a little loud, when we have a party in the kitchen we just plug it in a little further away. It has be very fun to create all kinds of creations and I love how easy it is to clean up.

100% YES!

I upgraded to Max and couldn't be happier. Everything that kept me from using my 1st Slushi is fixed with the Max. So fast, and enough for a family of 4 to have a drink with a top up as well.

As advertised

Does its job perfectly. SlushAssist = no guesswork and perfect slush. Yes, it’s fairly large and heavy, but easy to use, easy to assemble / disassemble, easy to clean.

Great for family

Makes perfect slushies, large capacity so works great for our family of 5 for everyone to get a drink! Easy to clean and makes slush in about 15 minutes give or take. Easy to use and adjust to your consistency.

Tasty and fast, but far too loud

The Slushi Max works well, but is too loud to use for any significant amount of time. Within 15-20 minutes of use, all my guests request for the machine to be turned off. This kind of defeats the purpose of having such a large volume of slush, since it becomes too annoying to enjoy for an entire party.

requires too much sugar

it requires A LOT OF SUGAR! I mostly do sugar-free and it didn’t work until I added Monk fruit. Sweetener to my mix. Which tasted very, very sweet and two airy. None of the recipes that I tried. Worked quite well. Just wasn’t worth it for our household.

reply from SharkNinja Product Expert

Hi there,<br /><br />Thank you for your feedback. We&#39;re disappointed to hear that the SLUSHi didn&#39;t meet your household&#39;s needs. To create the proper slush texture, recipes must contain at least 4% sugar. If the sugar content is too low, the unit will alert you and may not produce the desired results. While sugar-free or low-sugar liquids will not work on their own, alternatives such as honey, maple syrup, or coconut sugar can be used as long as the 4% minimum sugar requirement is met. We appreciate you sharing your experience and will be sure to pass your feedback along to our internal team as we continue to improve our products and recipes.<br /><br />Kind Regards,<br />Ninja Kitchen

Fire danger

We were so excited to try our new slushie XL machine. I left the machine on the counter for a day and a half before using. My son came home from school excited to make a slushie. We plugged it in for the first time and I heard a pop, then a hissing sound. Smoke started coming out of the back of the machine. I unplugged it but it continued to make the hissing sound and the smoke got worse. I was able to get the machine out of the house and onto my porch. By then there was black smoke spewing from the back of the machine. My husband pulled the machine off of the porch and onto our patio where flames started shooting out of the back. My son got some water and threw on it to put the fire out. I don’t normally write reviews but I felt that I needed to let others know about this potential danger. If I had not been right there with the machine it could have burned my house down. We were basically 3 minutes from the time of plug in to flames. We are so disappointed. My boys were really looking forward to making slushies!
