This thing is REAL!! If you have problem with accumulation in your toilet bowl , trust me , take it. Do not put too much and make sure to wear mask and open window. It is a STRONG smell that 'kills' everything around. But it works. A bit of high price, but what can you do ? Sometimes you have to pay to get it done.
