Electric Knife Sharpener by Kai, packaging has been opened but the device has never been used. Note that the plug on the device is a European plug but it comes with a UK adaptor which the EU plug slots into so it works as if it has a UK plug (see photo). I purchased this from Borough Kitchen over a year ago but never used it as I ended up being gifted a manual sharpener and didn't get the chance to return this. I assume it's all in working order as it is from a reputable company but as mentioned, the packaging has been opened but never turned on or used.
