A sanitizer that does what is expected of him, and that really seems to work. I live in a fairly damp house with mold problems (despite daily ventilation) and was subjected to daily attacks and allergic rather violent. For 15 days now I use it every night 2 or 3 sprays per piece, I feel a distinct difference, my allergic attacks have not completely disappeared but are much rarer and less violent. Attention to sensitive nose when spraying, perfume oils is strong enough, it is better to leave the room 2 minutes long it spreads. The smell that it leaves is quite nice.
