If your machine has a working steam wand, it will out-perform any automatic frother for hot milk.
Why the wand wins
Steam injects air and shears it simultaneously. The vortex breaks large bubbles down into microfoam.
A frother whisks air in mechanically with no shear, producing foam with visible bubbles that separates within a minute or two.
That difference is the whole gap between a flat white and a cup of hot milk with froth on it.
Where the frother still earns its place
Cold foam for iced drinks, which a steam wand cannot make.
Volume. Making four drinks at once, a frother runs unattended while you pull shots.
Plant milks, occasionally — some behave more predictably in a frother than under an aggressive steam wand.
When the wand is weak. Some thermoblock machines produce steam too feeble to texture properly. A frother is more reliable than fighting them.
The panarello caveat
Many entry machines have a panarello — a plastic sleeve over the wand that draws in air automatically.
It produces bubbly foam rather than microfoam, by design. Remove the sleeve if you can; the bare wand underneath is a proper steam wand and it will texture properly.
That single change transforms milk on a lot of cheap machines.
The recommendation
Learn the wand. Two or three weeks of daily practice, and the frother goes in a drawer.
