It worked well for about 11 months! Now it is in the trash, except for the battery!
Final Update: A ring seal slipped out of alignment, creating an air leak, causing the water in the reservoir to spray out the sides. When I opened up the device I noticed several very cheap plastic tabs, responsible for maintaining the seal and stabilizing the attachments, were broken, being held in place only by a corresponding screw. An item with, supposedly, a five year warranty did not even last a year! The company no longer advertises this device on its web site, and has not responded to a complaint email.<br /><br />Update: After less than a year of use, the reservoir now develops a vacuum during use. If the vacuum is released, it leaks all over the place the remaining water. This started a few days ago. No idea how to get warranty service, since the company does not even mention its irrigator on its web site any more! There seems to be no way to take it apart to service without breaking something. Disappointing. More Chinese junk!<br /><br />The high speed is quite forceful, so you have to move quickly. The water reservoir is ample to do the whole job. It is light weight and the on/off button is conveniently located. The LED control lights are bright, so there is a bit of bleed between option indicators. The reservoir is fixed to the unit, but it does not appear to be difficult to clean or disinfect occasionally. Lots of attachments, most of which you probably will not use, contained in a convenient case. It looks like it will travel well, but time will tell.
