I am 17 years old and I write this review with honesty I use this for a month and it works smoothly I used for only trim not for shave because my skin is very soft in past I was used this beard philips trimmer with not with combs I have alergy where I use this trimmer in my face and I not advice to those who use trimmer for first if you are using you first of all apply combs and overall I advice this is good and I suggest you to buy this trimmer for you beard but the build quality is medium not very good medium and this trimmer is not waterproof iam only angry with this philips there is charging light indicator but not charged indicator and the charging cable is very small and also the three combs are not adjustable and very bad thing after 8 hours charging it gives only 30 minutes but power is very good and I am comfortable with this budget and overall Good I suggest you to buy.
