High on the border

We already had such a ball at our subsidiary in use. This was now technically engine after less than two years the ghost. As our little one has a bulb to fall asleep, we bought again a disco ball. This is now already a few weeks in operation. Unlike its recently extinct predecessor the ball is substandard. They relatively rotates according to what you certainly do not hear while playing party music. The ball also wobbles slightly around on the journal.
But quite suitable as a party gag for about 20 sqm large room broadly. High I do not think that the ball is over the period of 2 years.
