Review (4/5): Beard trimming
The T980 works very well for a consumer-grade device. The batteries last much longer than necessary (at least, in the first few months of ownership) but using the trimmer corded isn't a problem. And it's a snap to use.
There are a couple things you should know. First, the highest setting is about 3/4" so if you want parts of your beard longer, you won't have the automatic height setting available. Second, the shaping parts around the cutting head are all plastic, so this device wouldn't last long in a professional environment (where it might get dropped).
The vacuum collects perhaps 90% of your trimmings. Plan on changing shirts after use. :)
