I bought this in tandem with a Magimix M100 nespresso machine to replace an old espresso machine with a steam wand that was on its last legs. Part of the resaon I bought a simple nespresso machine was that I now mainly drink espresso and black coffee but I wanted the option to make a latte or cappucino style coffee occasionally. This unit was recommended to me and it is value for money or cost effective.
While the milk foam is good it is still not quite as good as the foam I could create with my old, very much budget, machine with skills acquired with the right tools (stainless steel jug & needle thermometer) and lots of practice. I think the difference there is you are creating the foam with steam & air, this unit is jsut heat plus air.
On the plus side this machine is very, very easy to use. Fill with cold milk (as mentioned elsewhere the maximum fill line is a little hard to see), put the lid on, switch on and leave it to it. Takes about a minute to create enough foamed milk for a decent sized cup or 2 small cups. Shuts off automatically and it does create fairly dense foam. Perhaps not as hot as some would desire. Make a cappucino or latte is then just a matter of pulling your espresso shot or shots into a large cup and spoon/pour the milk over.
Other plus points - the jug, rotator and lid are very easy to clean. As this works by induction the base unit simply needs a quick wipe if anything is spilled on it. Generally a simple and ingenious solution.
For an occasional user like me and used with something like a nespresso machine this works very well although would struggle to make 3 or 4 cups quickly. Overall, a very good solution but not the perfect microfoam some would desire.
