Powerful Frother and Great Value
Color: P-Stand & Storage Cover Black, Size: Prestige Rechargeable
This little frother was a great find and value. Super happy with its performance. It has two speeds available, but I’ve only needed the lower setting because it’s so powerful. I’ve tried two other brands (one cheaper and one more expensive) and this one is by far the best! I’ve had it for 3 weeks, use it daily 2-3 times per day and it still hasn’t needed to be charged.

Easy to use Easy to charge High quality Frothier would recommend
Color: P-Storage Cover Black, Size: Prestige Rechargeable
This works insanely well. I use it every night for making ninja creami ice cream smooth for the next day. Easy to clean and very reliable. The speed is good and recharging is very easy as well. I would recommend this frothier to who ever needs to a hand held mixing machine thats easy to use.

This is the one!
Color: P-Storage Cover Black, Size: Prestige Rechargeable
THE BEST FROTHER!! I use a frother every morning for my skim milk and have gone through several. The battery powered ones I’ve bought work but end up bent and wobbly. I’ve had other rechargeable frothers that don’t have enough power to froth milk more than one day or two. This one checks all the boxes! Comes in a protective case and holds a charge for over a week w daily use. It is so strong I use the low setting for frothing and it makes a beautiful foam top for my coffee. Also use it to mix protein powder into liquid as well as other powders- no lumps! You could easily whip cream w this thing! Highly recommend!
