I received the Gillette Mach3 refill pack with 20 razor blades at home. The handle easily clicks into the head, which is housed in the plastic holder along with the other spare blades. One blade gives you about 15 shaves; so, one pack easily gives you 300 shaves. During testing, I noticed that you can use the razor with or without shaving gel or foam. I do recommend wetting the razor thoroughly before shaving if, like me, you don't use shaving foam or foam. I use the razor specifically for shaving my armpits, bikini line, and legs, and I prefer to shave without shaving gel or foam in the shower. The razor has a blue lubrication strip that ensures smoother gliding over your skin. It also protects your skin from irritation and redness during and after shaving. The razor has three thin, super-sharp blades. With each stroke, you practically shave each hair three times, resulting in a beautifully close shave. After using the razor frequently, the lubrication strip fades, indicating that the blade (the shaving head) needs replacing. I like the handle's color design: matte gray with black rubber ridges. It's comfortable to hold, and the rubber ridges prevent slippage when wet, giving you a better grip while shaving. The results are impressive; I haven't had stubble for a day or a day and a half after shaving. However, I prefer a razor with more than three blades.
