Love this frother! After extensive research on debating to buy one of the expensive electronic ones I ended up trying this manual frother based on the reviews. I didn’t expect much based on the cost but I do trust Ninja products and wow - I love this frother! 1.) The glass is pretty thick - not sure how people are breaking it so easily (from negative reviews). 2.) I hand cleaned mine (verses using Dishwasher) as hand cleaning is recommended by the company - took about 3 min extra to do. Easy! 3.) Directions super easy to understand, well marked on glass, and worked to a T! As for the negative reviews of milk coming out top, I turned the lid exactly to the spot specified on the directions sheet and it worked perfectly staying solidly locked in and no milk spilled over. 4.) For Heating the milk, I just heated my milk up in a seperate mug and then poured into the ninja frother...worked perfect! Both cold milk and hot milk frothed great. Overall I’d say this is a great product! I do suggest being a little gentle with everything (no slamming, banging down on the pump) and taking your time to effectively follow the directions. Doing so is super easy and takes a few min to have perfectly foamed or thick meringue style milk (what I wanted- cappuccino style)! I only wanted meringue style cream and after 15 pumps with regular organic 2% milk it was perfect. FYI the milk looks thicker than the picture really conveys and was about an inch thick. Also I already bought two more for gifts because I love this product so much!

Growing up in the in the Southwest I became an addict to a slushy produced from a store that was open from 7 to 11. As a make believe grown up, I am addicted to going to a particular coffee shop that people love to hate, but I like their frozen coffee drink. Plus, when I get back home, I go to my favorite burger place and get their milkshakes. We are planning to move to Spain in two years. Since the places I go to for these drinks do not exist in the town I am moving to, I decided to buy this machine, since it is available there too, to test and try out recipes so I can make these drinks when I am there. So far, I have tried out Slushy mode on several drinks. Starting with coke and punch from the market. I also used Frappé mode for store bought drinks in the bottles that you can buy at the market instead of the specialty coffee shop. Plus, boysenberry for a slushy drink that needs to be done on Juice mode. Lastly, I have also made milkshakes from flavored milk. What a joy! Following directions from the short recipe book I have been able to create my favorites. I have discovered that it is best to follow the recipes if there are some. Boysenberry was tricky. It is a juice, and the machine has Frozen Juice mode. However, the first try it did indeed freeze it so it was not slushy and I had to take it apart in order to get the juice out. The machine does allow you to adjust the temp. The next time it came out perfect, but I did have to play with it to make it so. My daughter, who will inherit this machine, since I cannot bring it to Spain, bought me recipe books for the machine. So far, this machine is magic. I am addicted to the drinks I can make with it. For now, practice making the drinks here in the states. When I move to Spain, I plan on getting the same machine there and making my drinks to enjoy.
