Hi. I would like to introduce you to the product catalogue of a reliable online shop where I purchased the Revyline Portable Oral Irrigator revyline.ae/. It has five pressure levels from 130 to 760 kPa, five nozzles with the basic configuration, a large reservoir of 240 ml, which can be easily removed and installed back. Very handy for trips and comes with a travel pouch. Recommended.
