Cool and Fun! – USB 3.5" Plasma Ball Reviews

Came well packaged. Doesnt create a humming sound when connected. The provided USB cable is pretty long, unlike other products seen online. Solid construction
Not meant for use in heavy daylight. Plastic quality could have been better.
Looks pretty cool in the dark. Opeartes off a 5V USB line, so buying a USB-Mains adapter may be suitable. No hum was observed during operation. The gadget uses a small flyback transformer to create the HV. This can create some RFI which can be solved by using a RFI choke on the USB line.
Makes a wonderful gift. Mine currently decorates my workbench, but will look good almost anywhere due to the novelty of the item. Must Buy!
