Review title is Water flosser [SEP] Using this item made me feel like I was in the dentist's office. It was easy to setup and use. I plugged the poer adapter in, filled it with water, added the nozzle until it clicked, and pushed the dial to turn it on. There are different nozzles and in the instructions it says one is for general use, one for periodontal pockets, and another for fresher breath. There were some other accessories as well. It comes with a storage for those accesories. I used the general use nozzle and noticed that the dial has no arrow to tell you what strength you're putting it to, you would only know while the power is on and the stream is going. On the lower setting, the water was spurting, not flowing smoothly, but did on a higher setting. There is a suspension control to pause it while using it. After you are done, it instructs you to dump the water. Overall, it worked as it should and I gave it four stars because of the spurting and no arrow on the dial.
