The best thing I have bought so far, but be careful.. it may not come set up and you might have to adjust it correctly so it doesn't pinch and irritate.. so from the moment it has the ability to customize it as you want and cuts deep, it's the best for me, very powerful battery that in just 90 minutes gives you the ability to use it for 3.5 hours, you really think the battery doesn't run out with so many hours you can use it, it says 8200 rotations and from what I saw it can reach up to 8500 if pushed fully otherwise it goes up to 8100, it also tells you that the motor lasts for 1000 hours so you know that such a tool will definitely be like you bought it on the first day, it doesn't mean that just after 1000 hours it will break, it can take 3, 5, or even 10 thousand hours to break or not break at all, but the best part is that it has adjustable lengths for trimming or cutting beard and hair, so in any case for the money it's the best trimmer you can buy for whatever use you want!!
