This came charged and was easy to use. I love the double sided razor concept, it made it easy to shave upwards and down at once. The speed is amazing getting enough hairs each stroke. It made it easy to get a clean shaven look by simply holding the skin taut. The battery life was well, I used this for half an hour, and it remained speedy and effective. I also did not find that my skin got irritated. It just felt smooth afterwords but irritation wasn’t my biggest concern as I would have applied an aloe gel to soothe the area If i found any irritations. Overall the quality was nice. Although, I will say I was expecting a small bag to be able to set the razor in after shaving since it just came in the packaging.

Does the job

Simple, does the job, but is pretty loud. It comes with a cable and a stand. Now, it does not leave you with a close shave so it’s best for maintenance or pre wax.

Didn’t last 5 weeks

Would not shut off. Had to wait for the charge to stop. Of course it happened 5 days after the return date.
