When you're hard at work at your desk there are few greater disappointments than taking a slurp from your tea of coffee only to find that it's gone sickeningly cold & clammy. It's easy to lose track of time when you're browsing Facebook, er we mean analysing spreadsheets of course, so make sure that next time you reach for your Java it's as steaming as it was when you made it. Simply plug our USB (Universal Serial Bus) Mug Warmer into a USB (Universal Serial Bus) port & pop your mug or cup on it, & it'll keep your brew cosy & warm.
