Pros: I am 66 with gray hair. So I purchased the silver-gray color. Love the miniature size, quality workmanship, accessories, thin almost imperceptible tubing. Volume and four settings easy to manipulate with the device in place. I recommended item to family members, they are equally pleased. Cons: Not really a product con, but DO read the directions. It’s a precision instrument and must be treated with care. Easy to lose so be careful.
