Works great!
Color: Green
Works great and doesn't pull hairs. The guards are helpful. The battery has last me a very long time. If you have a baby or child this would be a great option to cut their hair because it isn't super loud like regular razors

Good product!
Color: Gold
This is nicer than I expected honestly and a good value for the money. Trims amazing, the shave isn’t as close as a razor but it helps in a pinch! Charging takes forever but then it also runs on that battery for days!

Versatile trimer
This electric trimmer is very easy to use and, best of all, it includes a great attachment for trimming nose hairs. Everything feels high quality, it doesn’t irritate the skin, and it’s also very powerful.
