very Pro 4

As you can read on the device, the Pro side is immediately put forward, and this is confirmed for use. The 9000 series is of good quality with a highly efficient precision wheel (without risk of inadvertently changing the setting during use).
Beautiful autonomy, power and efficient cutting fine titanium certainly. Real good equipment with a cleaning brush. A former for sure, but I think quality. Water is the enemy of quality electrical appliances and a brush perfectly cleans the shaving heads. The shoes are made of plastic, it can seem a bit basic, but the mount is very good, ensuring real stability. That's for me.
