This is the 2nd unit of this type bought the brand Oral B. Some details have been improved in the storage space but it remains quite difficult to clean and fragile (eg fixing the cover) Brushing is effective. The irrigator is gentle and effective spraying position but the single jet can be aggressive to the gums. I hope that the joint of the water tank will not end up fleeing as on the previous model. I have not yet received to date reimbursement of 50 Euros the promotional offer.
