Beware of Bikini Trimming
Color: White
This shaver is very sharp, On dry skin it shaved my legs so close that it felt as if I had silky smooth legs as if I had used a high quality cream, almost slippery. My underarms however were a little sensitive to deodorant after. I must have misunderstood the description as I thought there was a brow trimmer accessory included, not, just the nose hair trimmer which is ok. Don't really need that, needed the brow trimmer. All this review put together makes me think this was made for men, or trans.

Buy a different one
Color: White
It looks nice but the trimming is garbage. The smaller trimmer l like for eyebrows or close shaving facial hair is worthless. You cannot get close enough nor can you see what you’re doing. You also cannot get right on the edge for precise edges for eyebrows for instance because of how it’s made.
The seller does not allow for simple drop off returns either. Too much of a hassle to print labels and too costly for ups pick up. A waste of $20.
Buy something else.

Great Product
Color: White
I’m honestly really happy with this purchase! This 3-in-1 bikini trimmer came exactly as expected and works super well. It’s easy to use, lightweight, and doesn’t feel cheap at all. I like that it comes with different attachments so you can switch it up depending on what you need—that’s a big plus.
It trims smoothly without pulling or irritating my skin, which was something I was worried about, but it handled everything gently. The design is cute and simple, and it’s easy to clean after using it too. For the price, it’s definitely worth it—you get good quality without spending a lot.
Shipping was on time and everything came in good condition. Overall, I’d definitely recommend this if you’re looking for something affordable that still gets the job done right!
