All in one device is convenient. It also makes it too easy to hit the start button before you are ready. I have shot water all over my mirror just picking up the device. Be careful!
Works great and does a wonderful job. The only thing I don’t like about it is that the control buttons are easy to change by accident when moving the device around to all the nooks and crannies. Battery life is excellent.
Water pressure is low compared to my last 2 water flossers (Phillips and plug in Waterpik). The water capacity is much smaller. I do like the new charging system.
After having the ION I find the WP-580 underpowered. But my wife thinks it's powerful enough but wishes the reservoir was larger. However, I do understand that it a more travel friendly tan the ION and thus some compromises are necessary.
