This is my 4th Slushy Maker by Chill Factory! Can make slushys and "margaritas"I wouldnt have bought 4 slushy cups if they didnt work but I would NOT pay more than $9 (on the high end) for these! $5 to $7 is what I feel this product is worth!REVIEW:This thing works with anything! Juice,soda,water,sports drinks make your own powdered drink,fruit punch,lemonade, COFFEE (make sure its already cold though)After washing it out (MAKE SURE (YOU TAKE IT APART AND CLEAN IT THOROUGHLY) and placing in the freezer(for first use over night) and the next day just pour in your desired liquid and squeeze squeeze squeeze (you dont have to use much pressure)In around about 3 minutes you will have a slushy (as i said I own 4 of these),but IF YOURS is not working as intended (as the first one I had purchased didnt seem to make a slushy the way I thought it could) I would return it for another one.NOTE and ADVICE: After following the directions if the product does not do a satisfactory job (i mean its NOT gonna make 7-Eleven slushy's) BUT IF it doesnt perform as intended you ******probably got one that has lost some of its cooling agent***** and in my opinion would make it a defective item (I should have sent my first one back) and thats what I recommend you do if it doesnt live up to its name.All in all the product WORKS and recommend it********ALSO take into consideration the size of the cup and the space it will take up********** ANNNND last but not least make sure the cup is dry before putting it in the freezer after washing it (INITIALLY AND AFTER EVERY USE) sometimes water gets in between the cooling agent part of the cup and the color outer silicone and ice builds up in between the two pieces (usually on the bottom) which makes the cup a little "stiff" because of that ice build up!4 STARS!!!The slushmaker itself does not work as well as I had hoped, but I have only tried it on diet sodas so far. It makes some ice but not enough to make an actual slushy. Again, it may be the diet soda. But I do want to say how impressed I was with the seller. After reading my review on the seller feedback page, they wrote me a nice, personable email -- giving tips to make it work better and offering a full refund. They even told me to keep the item because they wanted to spare me the hassle of returning it. I am truly impressed with their customer service--it is amazing!I purchased two Chill Factors. One worked great making the slushy. The other Chill Factor worked a little, but most of the liquid did not turn into slush. I liked the one that worked so much I decided to buy a third, hoping that it would replace the one that did not work very well. The third one only worked slightly better. After the three Chill Factors have been in the freezer overnight, I can tell which one is the best by just a slight squeeze of the empty cups.Update: I left all three in the freezer for a couple of days. Doing so resulted in great slushes from all three. I am now very satisfied with the product and have changed my rating to five stars. (The Chill Factor cups were in a full freezer at the time of cooling).Some drinks slush, others don't. I have a pretty cold freezer, but I can't get things like a sports drink to get slushy.Ive recently tried putting a small amount of water in the cup before I put it in the freezer, this makes things much better. Sodas and sweet drinks slush easy, but anything with more than a little salt content is tough. It gets super cold, but not slushy.I bought this for my wonderful son as a present.Its fun to use and makes the kid excited for ten minutes.Most drinks just get a few icicles at the top if your drink is not completely chilled.It will be fun if your drinks are nearly frozen and you have younger kids.Its kinda depressing if you are an adult and you bough this. P.S. this is not the dad, im the son.It worked well but the slushy was not what I expected. I thought I was going to get a slushy that you can get from 7 below, but it was an off brand of that.I really like this slushy maker. It's easy to clean and use, and hits the spot when I want a slushy without going out. The only complaint I would have is that I want more slushy! I would say that the amount of slushy this cup produces is about as much as you would get in a "small" sized cup at the store.IDK where this even is anymore after I moved, but it was fun while I had it. Kinda hard to clean, especially since all the slushies I made were from sticky sodas like Mountain Dew or Coca-Cola.
