Review (1/5): Where is their failure analysis
I have purchased four of these irrigators from four different vendors though all the products are essentially the same. They are all surveyed for quality assurance by Intertek, a world wide operation that does product analysis and assurance. However every one of these has developed a problem, usually within the first year and usually derived from some battery issue. I guess I am not too bright going back again and again in the hope (vain it appears) that the next guy is going to recognize the problem and fix it in their product. This one is no exception to the rule - it doesn't even work out of the box, apparently more a switch issue than a battery one. I am going to explore WaterPik now hoping they have fixed their small reservoir issue.
