I have been using the Cybersonic Electric Toothbrush for over eight years now. I love this toothbrush! It has been long lasting, dependable, holds a charge well, and just keeps on working. It is very easy to use. Mine came with two chargers and brushes so the whole family could use it. We just pop off the toothbrush part off and put on another. Each brush comes in a different color so that you don't get confused on who used which brush. The electric toothbrush itself is very easy to turn on, with the press of a button. There are interchangable heads that can be used too. I have the tongue brush, the flosser and the toothbrush heads. They are easy to pop on and off. The battery holds its charge well, too. It works great every morning, brushing my teeth vigorously. I love how my teeth feel after I have brushed, it feels just like I have went to the dentist and had my teeth cleaned. This toothbrush is quality that will last and is worth every cent that I spent on it. They are even more affordable now than when I bought it eight years ago and the improvements have been great.
