Review (4/5): Good, not great, with a flaw
The trimmer works pretty well. It trims my beard and moustache adequately and to the length I want, but not on first pass. Most of the trimmings make it into the collection chamber, but not all of them. I would say about twenty percent of the trimmings end up in the sink not the collection chamber.
This is a replacement for me for a T990 Norelco trimmer, with a dead battery. I now have to disassemble that trimmer to get at and remove the dead battery for recycling. That is a problem with this trimmer too: it has a rechargeable but not replaceable battery. When the battery no longer takes a charge, as with my old trimmer, the trimmer will not run even when the cord is plugged in. I would prefer a trimmer that is corded, with no battery, or with a replaceable rechargeable battery. What Norelco has done is created a trimmer with built in obsolescence. When the battery is dead, the trimmer is done for. And batteries are not environmentally friendly.
