Functional
I used to get cuts when using regular razors but ever since I switched to this electric razor, I no longer have to worry about getting hurt. The blade is extremely sharp yet gentle and provides a smooth shave on my face, legs, underarms and other areas without any pain. The waterproof feature makes cleaning easy. I can simply rinse it under the tap. The rechargeable design is also very convenient. It's small and portable easy to take on business trips and travels! The shaver glides smoothly on underarms and the detailer head gives perfect shaping for bikini lines. Fully waterproof for shower use and the self cleaning blades rinse effortlessly.

A little drying but amazing
First thing to note is this is a soap, not a cleansing bar, so it WILL dry you out if you use it too much. but the smell is irresistible, and it definitely conditions your skin well. I wouldn't say it has a slimy texture like advertised, but it is still really pleasant and the foam is so rich with herbal aromas. Definitely not a good value for the money, but I consider this like a luxury splurge soap bar for when I want to treat my senses rather than a daily driver cleanser bar.

Unfortunately, it has an unpleasant scent
I read the reviews and a few mentioned they were not fond of the scent. I decided to give it a try since I liked the ingredients and it seemed like it would compliment my skin type. Yes, unfortunately the scent is just way too much for me. I did not open the item or use it. Upon opening the Amazon shipping bag, I could smell it. I decided to return it. I'm disappointed, because it might be a great product. I do not want to put the brand or product down since I was unable to try it. The scent is just not for me.
