I purchased this new on Amazon, but I haven't had a chance to use it, so I'm selling it to declutter. I used it for about 30 minutes to check its operation, so it's practically new. When you turn it on, it moves in an irregular manner like a real snake. It has sensors, so it changes direction automatically when it enters under a wall, chair, or sofa. It's USB rechargeable. There is no outer box. Please ask any questions in the comments section.
