Stay away from this trimmer
I agree...with the negative reviews. I really like the guide on Norelco trimmers but that is about it for this latest model. I threw it away 2 days after I received it.  I practically shaved off my goatee after it switched from the 3 to the 1 setting by itself. The vacuum doesn't work all that well and if you travel, it is so easy to accidentaly turn this on as it just takes the slightest pressure on the switch to start it up. Bad news all around.
