Nice feel
Color: Matte Silver
Feels good in the hand. It has some weight to it. I like the fact you can change out the blades. Way better than the cheap plastic disposable razors.

Great Exfoliator
Color: Matte Gold
Beautiful gold color, nice ergonomic feel and weight. I had been using disposable plastic razors, and thought I would take a chance on this more professional styled one for dermal exfoliation as well as my eyebrows. This razor is sharp, but it is easily managed when start gently, you don’t slide it in a cutting fashion, just use it on taught skin, and lift it up for repositioning. When I did my brows, there was no evidence of hair growth left behind. AWESOME! This razor comes with spare blades as well as replacement parts if needed. It has a rubbery silicone cap to slide on and off easily, but not fall off creating danger. The razor has a small accessible prong to easily slide it out for replacement. It comes nicely packed with detailed instructions. I highly recommend this for anyone wanting to take a decade off of their skin. I would recommend a professional if you have any shakiness though.

Worth it! Solid dermaplaner.
Color: Matte Blue
It feels solid in my hand. The blade doesn't seem to be all too sharp, but it works... so maybe that's for safety purposes? I like it and will stick with it for a while.
