Review on Geekly Glowing Radioactive Elements by Generix by Chad Rosier

Terrible design product. 1) It requires far more pressure/weight than any large cup/mug can provide. I had to squeeze my hand with all my might to make even the light blink. 2) The sensor on the back of the stand makes it wobble and become unstable. I would never trust putting anything filled with liquid on this thing. You will be very disappointed if you order this and expect them to light up when you put a drink on them.
