I've owned this trimmer for a few years. My spouse & I both love it. The attachment is perfect for eyebrows. It's also great for trimming wayward ear hairs. That's really all we use it for. I only recently finally changed the battery because it sounded like the motor was slowing. It's been reliable & is well made. Since it's about the size of a tube of mascara, it's easy to take on trips or even slip in a purse. The trimmer & attachment both fit in the handy travel pouch. Love it!
