Who knows how long this thing had been sitting on the shelf. Clearly no one knew what it was or was willing to take the time to look it up because even though it was just $1, it sat there until I used Google Lens and eBay keywords to identify and comp this item.
Turns out, it's a USB 3-switch foot pedal from a company called VPedal. This item sells on their website for $75 and for about $40 on eBay. It's not a fast seller, but picking up items like this will keep your eBay business running profitably.
