Works great with soy milk
Amazing steamer with high volume capacity. I can make large lattes. I love that it let's you choose your temperature. I use soy milk, and it works perfectly every time. When using at max temp, only a tiny bit of soy milk gets a little burnt on the bottom, and it scrubs right off. Since the little whipping tool comes off on the inside, it cleans very easily. I love that the little whipping tool is magnetically attached, too. It's super easy to work with and very secure. My 8 year old uses this all on her own without issue, which proves how easy it is. Highly recommend.

Great frother choice!
I love this thing! As a former barista, this frother does a wonderful job! I've done hot and cold foam and they held up great! Used oat milk once and that did a great job foaming up! It can take a few minutes for the foam, so when I start my coffee, I start the foam, too. It's also dishwasher safe, which I love.

Burns On The Bottom
The chocolate setting takes forever. The milk burns in the same spot on the cup no matter how I try and rotate the cup during the heating process. I expected more from the reviews.

love it but...
Overall I like this product. the only annoying thing is that you cant put milk on max because it will spill and make a mess. Everything else is good and is very easy so clean too.
