I'm re-reviewing this item. I've been using it every morning and this morning I go out, put the milk in and turn it on. It made all of the same noises like it was working properly but that was as was it. It warmed up the milk but absolutely NO foam whatsoever. I tried it a second time and got the same "FLAT" results. Thankfully, I got the extended warranty so I ordered a replacement for now. We'll see if that one is any better..... 
This seems to be made well and I liked the way it makes foam! It's more like a whipped creme due to the height and how long the foam lasts. I've had other frothing machines and this one is far superior. It's much larger than I was expecting but on the weekends when I drink more than one travel mug of coffee it will be just fine!
