A truly amazing wireless gaming mouse that I was gifted when I first began to stream seriously. The Logitech G305 K/DA Lightspeed Wireless Gaming Mouse is perfect for online gaming and fits perfectly in the palm of your hand. It is lightweight and easy to use/program. I only used it a few times and realized that I prefer wired mouses. Sadly, the original box was accidentally discarded while I was cleaning the room. I will ensure that it is well protected when shipped. * I want to make your buying experience as relaxing and happy as possible. All items are cleaned/steamed before shipping. We do have two pups in the house, but I work hard to make sure that there is no dog hair on any clothing. Non-smoking house.
