this review title is: be careful when using this product and the content is: the issue i had with this product is you have to hold it upright so the water could get through the tube not easy to clean all teeth as a result the blue tip has a hole in it which made me think the water was supposed to shoot through it not so it shot off the devise and went to the back of my throat it was a choke hazard an easy fix is to not have a hole in the tip so it is not confused as anything other than a cap you are supposed to remove before use i was looking forward to using this product not the quality or ease of use i expected.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
