I can speak only to my experiences with this product. This razor / trimmer isn't going to work for every single person alive, because our bodies and likes are all different. So I can't promise you this will work for you. I, personally, have been buying these razors for years. I'll never buy another one so long as they don't change them. They do what they claim to do. I get a very, very close shave, the blades last a long time, the trimmer does a fantastic job, and yes, there is a moisturizing quality as well. Does the moisturizing gel on the blade last forever? No, it doesn't, especially if you get soap on the blade. But it will last a long time, and even if you have to start using shaving gel in the end, I haven't found the razor to be any less effective. Cleaning the blade is simple, but yes, it will eventually dull, as all blades do. That's not a defect of this product. It's just a fact of all razors. I have very coarse hair, so it's possible my blades may dull faster than others, but they still last a long, long time. The device is definitely waterproof, and the battery on the trimmer is well protected from any water damage. It, too, lasts a long time. I've found this razoe is great for traveling, but beware. There is no cover for the blade. I'm not taking a star off for this, because no cover was advertised. Just wrap the blade up carefully and store the razor. I've purchased these to leave in different places when I travel, and I've found that each and every one is worth the money spent and more. They work, they last, and they're very high quality.
