I use the trimmer for trimming my 1-2-week beard. That works wonderfully as far. The machine is not warm (certainly not hot). The noise is not unpleasant. The razor fits comfortably in your hand and all settings can be made good. The battery lasts long enough for my purposes. I shave about once a week and needs to load about every four weeks - so I just already eighth no longer on it since. The only downer: without top's is not really smooth. So you have to either live with the stubble or pick up the razor.
