USB Cup Warmer Hub

After constantly re-heating my coffee during sessions at my PC, the USB Cup warmer Hub seemed like an excellent idea. It was not made clear on the web site that the cup was not included, and none of mugs or cups are thin enough or flat enough to transmit the heat from the hub to the contents, even after some time sitting on it. My MacBook Air has only one USB slot and no slot for a CD/DVD so the hub aspect of this tool was an added attraction but to add to my frustration neither the external CD/DVD unit nor my Passport hard disc would show up on the screen. The hub is a useless waste of space and money.

This Cup Warmer hub could only work properly for cups with completely flat bottoms (i.e. no ridge round the edge). After buying this I realised that ALL my cups have such ridges, so drinks don't stay hot!

Doesnt get to hot so your drink is always ready to drink.
