Single Button Operation is not Ideal
Bought this to replace an older one (from different manufacturer) that started to develop battery problems. This one certainly works and does what it says. It's also well built and does not feel cheap. However, there are 2 things I don't like about it.<br /><br />1. This model (FTV40D) has only 1 button, which cycles between Low-Medium-High-Off. If you want to take it out of your mouth before the tank is empty, and for instance you are on the low setting, you must cycle through the higher intensity modes before reaching the off position. Cycling those higher powered modes might be too strong for comfort. And, taking out of your mouth while it's running will squirt water everywhere. My old one had separate power and mode buttons, which is more preferable in my opinion.<br /><br />2. The charger is a (very) cheap wall-wart type which is a bit fiddly getting seated into the connector on the device for charging to engage. I had plugged it in for a few hours only to find it did not charge and had to wiggle and rotate it to get a good connection. I question the long-term durability. Further, the power connector is on the bottom of the flosser, which means the unit has to lay on its side while charging. For comparison, the one this replaced had an induction charging stand that was simple and no fuss- just set the device on the base and it starts charging.<br /><br />If the above does not concern you, then you should be happy with this device.
