Only lasted 6 Months before the speaker blew out and it sounds like it was underwater, the black box ones last much longer.

Box is working fine except for the inverter 110 V power polarity is reversed so only using it as a Battery operated Bluetooth speaker the quality of sound is decent last for hours at a reasonable volume can be turned up to quite a loud volume producing a lot of sound

They say that if you make a shiny box with nothing in it that people would buy it; ION products are a great example of that old marketing gimmick.
