Battery Run Time is surprisingly long. I use it every 3-4 days and had to charge it up to now only a few times. I appreciate every 1 1/2 months.
The progress bar and the display of the cutting length are well implemented and reliably.
The only negative point: For me the cup for the collection container is already canceled, although I have treated the unit gently. A replacement will probably take 2-4 weeks and I could not bring myself there as long endure without beard trimming.
Update: Amazon gives me and a new device and only after that I have to return the defects. Excellent service!
