Traxxas 3946 VXL-8s ESC. Condition is "Used". Shipped with USPS Parcel Select Ground. Works but has a "sticky" power button. Meaning that sometimes the power button sticks when pressed, causing the esc to go into programming mode. Easy solution is to stick the button with a sharp object and lift it up as soon as you press it. So if you can deal with that or have a fix for it, this is a great buy. If you cant, dont buy it.
