It's a sturdy device having two different functions.
Pore is not a major concern, so I use normally ultrasonic to infuse my serums/creames.
There's a theory that none of the home device will show any difference and significance, so I think seeing visible difference might take a while for me.
However, I do still like to use this in the evening to treat myself, this just feels good.
The price also seems comptenet compared to other types of devices.
Hence, I recomend to the entry device users.
