After some time (weeks) fell shortly after switching from blue. All other colors go further. Is probably a bad contact or platinum defect. But since you can not stop the change effect, is just always times duster when actually would turn blue.
We operate the glitter lamp, either directly to the USB port of the CD-radio recorder or to a USB adapter for the power outlet.
Overall, it is a mixed product. If you can live with little quirks and low brightness, gets an extremely cheap (inexpensive would be nice told) effect lamp. I paid 3.50. Together with 1,95 Delivery costs makes 5.45. More it is not worth it.
