does the job, good value.
I liked the idea of not having to hold the water flosser full of water and this works fine, I just use a mug of water.  A reservoir would probably have to be cleaned and disinfected fairly often, with this, less to be concerned about especially travelling to foreign countries who do not have a secure water supply.  You could also use a small water bottle as your source.  The three levels are a bit soft for me, but the highest does do the job.  Overall, satisfied, good value for the money . I have only had it now 2 weeks.
