Shaver
Was hoping for a closer shave, but great in a pinch. Keeps a charge for a long time.

AMAZING BIKINI TRIMMER!
THIS IS EXCELLENT! It shaped me up really well and in seconds. It gets really close and doesn't nick you.

Quite useful
I got this for the wife and she has enjoyed it. Being water resistant has really been nice and the battery lasts quite a while.

Very impressed!
I love this thing! It has a ton of attachments. I don’t think I’ve used them all yet. I love the size, it fits in my hand very well. It seems quieter and seems to vibrate less than other ones I’ve tried. I haven’t gotten a super close shave with this, but I don’t expect to with electric.
One bonus for me has been because of its size and the fact that it’s not very loud, I’ve been able to give my senior ragdoll cat a much needed belly trim! He’s completely unbothered by this razor.
