*by F***E on Reviewed in the United Kingdom 🇬🇧 on 20 March 2018*

Bought on of these on Amazon a couple of weeks ago. Works well and I like the quirky styling and the machined from solid case. Simple controls, one on/off switch and a second button which is volume control and after a short press in, mode selector. (a longer press returns it to volume mode)
