I had in front of Philip and Remington devices - which can wrap up but.
Nothing comes ran to this linear motor technology.
I use it to Bart connection (without attachment) and haircutting (with the smallest came).
Equipment always makes an exact length, no matter how you impresses the device, or how firmly you press. Pressure is not necessary here.
The Panasonic has a cutting edge performance that is second to none. No zip or hair pulling more.
The only drawback, but negligible for me - who has so much power, the flying around the cut beard and head hair a little further ...
And wet cutting is not possible if you want to have the unit long .... it is not waterproof.
