I thought that the mark had been absorbed by competition

In the early 80s there was this unit in all pharmacies and dentists the advised.
I took him around for several years until the day when my bag was stolen!
Recently, trying to find this dental hygiene and massage, I bought what I found (concurrent mark) and it was not too bad at first, except that the nozzles were fouling very quickly. In short, as many users, after a few months clean break of the pipe flush with the unit.
This is by searching on Amazon that I found by chance this brand that I forgot the name, and returned all the power and comfort of there 35 years!
Sure fixing jets became a bit "light", but they hold well, especially the small moving part which prevents tartar from adhering kept all its effectiveness.
I have not tested the "new" (tongue cleaning etc ...) because it was not my first need.
In the process, I also bought the electric toothbrush I did not know, and she is very sweet.
I can not yet comment on its effectiveness, but it sounds very professional, and a bit expensive too.
