In my personal opinion, this is one of the best devices on the market and, above all, Mr Röck (manufacturer) is very good at communicating the health benefits of oxygen ionisation.
But now for a comparison with our device, the AG 2.0:
Their price is 3 times as high.
Their output is only 12 million, whereas we produce 200 million per cm³.
Since, according to their own statement, only about 200,000 anions per cm³ are inhaled, I wonder whether 200 million in the room are not better than inhaling a few hundred thousand, whereby the inhalation only runs for a maximum of 90 minutes, but our 200 million are there around the clock?
