The product is well designed and easy to use, the spoon that goes with it is really useful. It apprehends the beginning you say "you're not going to put you in the nose that still not kidding ...." and then once water begins to flow into the other nostril we say it will it ' is not a torture I find it even more enjoyable. I suffer from allergies, chronic rhinitis and sinusitis and sometimes after spending fortunes found in spray style pharmacy STÉRIMAR I thought seeing this watering why not ..... the result is even better than I hoped for here you really feel that the nose is clean compared to the spray remains superficial. as they say others: well we wash teeth and ears so why not the nose ?, especially for people like me living in big cities to breathe exhausts, pollen, cigarette smoke for those who smoke. Apparently the lota is still little known in the West as anything with all the means that are available today we pass off things simple and effective; I definitely recommend this product.
