Question: Would this work for milk substitutes such as rice milk?  What about half and half?
Document: I am pleased with this milk frother, I received it earlier than the expected date. You have to fill the frother half way. Too little doesn't work, too much doesn't froth well, but you will have a mess.Milk has to be cold-  Once I got the hang of it, It enjoy it. Only complaint- my arm gets tired. otherwise- Great product
This frother is well made and very easy to use. The froth produce is as good as it gets. I have tried Half & Half, 1% and 2% milk and a blend and all of them work great.I fill half way up the base, preheat the base on stove top and then attach the top, pump ten times and walla, perfect froth.Truly amazing.
This does work but you have to ensure that 1) you have it full at least half way 2) your milk is not too hot. I thought that hotter was better, but actually I find that when my milk is just barely hot, this is the perfect temperature. Also - you need to pump several times, maybe two dozen, going all the way to the bottom and then back up. This gets you TINY froth bubbles.
This frother is extremely basic, which is a plus as far as maintaining it goes. I put it in the top rack of the dishwasher, and it seems to be holding up fine so far. And, as long as you are frothing a large amount of milk, it does the job. If you use less than half a cup, though, the air doesn't flow through the milk enough to froth it. Additionally, it does not work well when using warm or hot milk.
I fill it up half way with the cold skim milk. I would highly recommend this product.
I have a friend who is a foam snob. He says this isn't good enough for him, so if you're in that elite category look elsewhere. For the rest of us mere mortals this frother does exactly what it says, it froths. It froths cold milk as well as hot, with more froth coming from the hot milk, and it works on skim. I wish it was microwavable, but then it would probably not be at all durable.I learned right away to avoid filling it over half.
Pretty simple to use and not a lot of parts that can break. It isn't quite as good as an espresso machine with a good steamer but it's more than a sufficient substitute. It produces a nice thick micro foam. I haven't noticed a problem using it at 1/4th full, but I would imagine that 1/3rd or half full would be fine too. probably don't want to put anymore than half way though. Also, good to warm the milk first.
This is a great manual milk frother but It doesnt make a much froth as I want for my capaccinos. I would say get this if you don't want to spend the money on a fancy exspensive one but know you might have to work a little harder for your bubbles.
I love this little thing. I fill it about 1/3 of the way up with warm milk (microwaved usually, but if I'm not feeling too lazy I'll heat it on the stove) and froth away. I take it to work with me and I don't have to worry about breaking it as I would if I had a glass one.
I ended up with aBODUM Schiuma Black Turbo Milk Whipthat I'm very pleased with and it's just about half the price of this thing.
Answer: This works best with whole milk.  I tried 2% milk and I didn't get the froth consistency that I prefer for my cappuccino.  I have not tried any other milk substitutes, so can't say for sure if it will or will not work.  My suggestion is to try making it in a jar first (put warm milk in a jar and shake it) to see if it froths.  If it does, then this milk frother will work.  I really love this milk frother, just a few pumps and you have rich/thick froth!
