Review (5/5): Works as advertised and better
I have been using a Norelco T370 trimmer for several months. I bought it for the mini-shaver initially, decided to grow a beard, then trimmed the beard with the beard trimmer attachment. It did a great job of shaping and trimming, but left a mess of clippings in the sink. After reading a million reviews, I decided to try the T980 for it's vacuum feature.
The T980 is great! It does a perfect job of trimming my beard evenly (setting at 7, ultimate beard length to be a 9). The best part is that about 90% of the clippings go into the vacuum receptical with only about 10% being lost. I have not come across any of the negatives (adjustment slips, tugs hairs and on and on) mentioned in other reviews. Unlike my T370, this trimmer lets you know when it's fully charged or about to go dead, and even if it does die in the middle of a session from a dead battery, plugging it in finishes the job. Most other trimmers only work when charged, not on house current.
I can't think of anything this trimmer could do better. In my estimation it's looks, design and operation are flawless. The clipper works well on my beard's 'neckline' and the mini-trimmer keeps the bottom of my mustache trimmed perfectly. I really think the T370 does as good a job trimming as this one does, but will not run with a dead battery when plugged in, and does make a mess with beard clippings all over the place. For those two reasons alone, this trimmer is a BEST BUY!
I am not putting the T370's abilities down in any way. For the price it can't be beat. It trims well and the mini-shaver is still the best way to shave the short hairs on my cheeks above my beard on a daily basis. I use it daily along with the T980 and will continue to. They both have their place. If you don't mind the beard trimmings everywhere, you will be happy with the T370, however if you are serious about perfect beard grooming (and I DO mean PERFECT), with none of the mess, both tools are a must.
