I ended up going with another brand, which I returned because it was impossible to insert the batteries into the too-tight compartment (other reviewers had the same issue and I should have listened). So I bought this one and not only is the battery compartment ample size and easy to insert the batteries into, the company even sends you two AA batteries to start you off! I also very much appreciate the fact that you don't have to hold down the button, just push it once to start and push it again to stop. It's powerful and I love that it sits in its own stand and looks nice in my kitchen while doing so.

Great frother with storage cap

Perfect frother. Powerful and fast enough; great for making cold foam. Battery has lasted several weeks for me so far! Easy to clean. I love the cap that comes with it for storage.

Froth yourself 😁

I love this little gadget! I can make frothy milk chocolate or chai tea at home now! It froths very well, especially with warm milk. It’s easy to use! I think the price for this is great and it’s a good value.
