I was perusing eBay for a cheap backup/side project transformer and when I searched for a Volt 300W VTR-300SL-SS-R1, the search returned listings with a part number NBTR-300SL-SS-R1, without a Volt name on the unit. However, the unit looks nearly identical. A google search does not turn up much. Is there any knowledge around this specific part number? Is it a knock-off, is it legit? The price is right for a backup.
