Review on Geekly Glowing Radioactive Elements by Generix by Mido Taylor

I bought some of these over a year ago and they have been great! Now the design has changed and they are useless as coasters. They turn on and off depending on whether a mug is placed on them. Now you need to turn on and off the switch on the back manually. This eliminates the cool factor completely! Also, turning it on and off manually every time you use it isn't practical. TERRIBLE CHANGE!
