The shortage of "Luminarus"

A glass of "Luminarus" is a complete shit in a beautiful wrapper.

LED lights can be turned on and off when, for example, water drops are in the glass. It is necessary to wipe the glass each time dry before you put it on the shelf. This is utter marazam.

The backlight can also not light up when you take the glass in your hand. In other words, the LED already the next day after the purchase behaves completely inadequate and lives some kind of unknown life. When this glass can not be used in the microwave, and in the dishwasher it is always on. Return the money!
