The first mouse, the well-known Attack Shark, comes with its dongle. The Attack Shark mouse has a scroll wheel, which is the wheel in the middle of the mouse. If you press it, it clicks, but it doesn't scroll. However, the mouse in general is legendary. Secondly, it has mouse skates installed for smooth movement, and I just installed them today for both mice from Corepad. You can search for mouse skates and see. I installed them today. The second mouse is the M85. When you buy the mouse, you don't feel the smoothness, but I installed skates for it, and honestly, it has incredible smoothness. The third is a mixer, working, with its box and all its cables. Honestly, all of them are working perfectly. The reason for selling is the need for money; otherwise, I wouldn't sell. Attack Shark mouse for 90, M85 for 70, and the mixer for 50. If you want all of them, instead of taking them for 210, you can take them for 170.
