I am delighted with the purchase of this travel irrigator. It has an easy to fill tank, collapsible for storage of sufficient capacity (165 ml) .Its jet power is comparable to that of its counterparts on secteur.Il has a range of at least 2 weeks for battery with a bi-quotidienne.Son acceptable space use, can store it in a kit toilette.La delivery is fast although it is shipped from a site based in Germany.
