The product is suitably small to fit in a small space. It is nice, silver-colored, and fits well in the hand.
This product is quite good for beard styling in my opinion. It is easy to do precise work due to the thin cutting head. For hair trimming, it is not really suitable, at least not for me.
The device's locking function is handy so that it doesn't turn on by itself during transport/storage. It locks by holding the power button for about 3 seconds, and unlocks by holding the power button. With the included cutting head attachments, you can cut to 1mm, 2mm, 3mm, or 5mm length. These pieces lock easily onto the cutting head, but they should have some visible transport box, now they just come in a paper bag. The device is easy to charge thanks to the included charging dock, but it does require a power outlet nearby.
I think the device's functionality depends a bit on hair type, it didn't work great for me.
