The 250Hz Screamer has the added bonus of a series of precision-drilled
holes around the rotor surface to produce a satisfying whine even at lower speeds!

The Screamer used in an office environment is a great way to loose your job, but its great fun

Also included are full operating instructions, 2 starter cords

Note: Not to everyones taste, very loud
and we do not refund if you simply dont like the Screamer.
