I love this razer and these blades.Im 38, used every kind of blade known to man. Even have the trimmer from barberology and that does line you up amazing, esp if you dial it in perfectly. However, it will cut an nick the heck out of u if until you know how to use it lol. I typically use this over that, for ease of this product. That gives a straighter line, easily, because the blade is wider. So a typical trimmer is always good to have to make the line. This works just as good if you take ur time, for an absolute fact. I have an excellent barber, who knows how to line and he always says I'm one of the few that has a good line for him when I come in because I keep it fresh in between cuts.Just be absolutely sure you are not buying the blades meant for first time (young men) shavers. As those are not nearly as good and effective as these blades.I have used these consistently for years now.They line you up, almost perfectly.Obviously a straight razer or something like that will take it down all the way.I shave about every 3 days or so with this and I don't have all the in grown hairs I used to always have, or irritated skin or cuts from these.The only time this could cut you, is if you use it on ur jewels and don't perfectly straighten out the very delicate skin that is there, you will get nicked for sure (ask me how I know).If you're careful, it can be done.I occasionally use this to shave my arms and stuff like that, it takes many passes as this wont remove bulk hair like an barber shop style blade, but it will do the job with persistence.Anyway, this is a fantastic product that has lasted me forever, seemingly.These blades easily last me a couple months. You can push it much longer, but when they really start to wear, it takes much longer to remove hair, and it will occasionally pull some hairs, which is obviously uncomfortable.Great product though and a great price for what you get.My razer is easily about 3 years old, and its a bit louder than it used it to be, but its still effective and works.They are cheap to replace if needed tho.Take care, hope anyone on the fence purchases.
