Plus: safe formulation, a very pleasant smell. CONS: the instability of the smell. I really liked the scent of air freshener. Perhaps, in pleasantness to me he is in second place after the smell of Indigo Wild, Zum Mist sandalwood with citrus. In third place (again - for pleasantness) - Air Scense, Lavender. In general, to find a natural air freshener with a delicate aroma - a big problem. I could not do in Belarus. On the market are only thermonuclear Ecodoo and the Amway, last I buy did not dare, after reading reviews about it vigorous. Here - smell thin, but at the same time, copes with unpleasant odors toilet room. With regard to the design or the need shaking before use - no problems with that, neither I saw the other. robust design. And yes, it is necessary to shake up just about every natural freshener, because most of them are made on the same principle: the slurry contains aromatic oils in water. I think, for the opportunity to use safe means without harm to health - not a sin and a little tense. More reviews - on my page The-best. Hopefully, they will help you to choose only the best on Ayherbe. I would be grateful if you press the YES!
