This are lightweight and durable. Well-made and heavy duty. So easy to use. It is just the right size. It fits in your hand perfectly for use. This set come with 8 different guide combs, its can easily be changed, to get the exact length needed. While using these, they only have a faint humming sound while using them. I really like the size of this. So easy to use. Great to have on hand. It is really nice that these are wireless. Love that design on this. Perfect to use for hair or beard. Once this is fully charged, it can last for up to 3 hours.
