The toothbrush is working properly and is very thorough, especially when compared to the older predecessors. The irrigator is fine, the pressure I find adequate to the gaps to get clean. The design is a bit strange ... but who is on gray glitter look is here to the right place ... I can not say anything, the device is only more than a month in operation, at this time everything perfectly on the shelf. It is interesting that you get by Regis animals at Brown one year warranty extension, the thing is certainly worth.
