The best thing there is in a machine, don't listen to what most people write, it's fake. When you get it, it shows exactly how many hours it lasts. Specifically for me, it actually lasts as long as it says, 5 hours with 2.5 to 3 hours sometimes. It charges quickly. It's the best thing you want for trimming, shaving, etc. You want to shave your beard, and even with the combs it has, you can cut it to any size you want without using the big machine because it has 1.5 and 4.5 which is the best. You want to do details or cut stray hairs, it's the best. At first, until you get used to it, maybe 1-2 times, when you use it for details on the neck, etc., you might feel a little bit different, but it depends on the skin. Personally, it suited me and it's the best for its price. I highly recommend it!
