First the Slim. Since we travel so much, the Slim Sonic Toothbrush is a must have! Violife offers a ton of great colors to please anyone, we choose the Mirage. Not only is it a great accessory, but it is a phenomenal toothbrush! The Slim goes at 22,000 brush strokes a minute. It also has a wonderful mascara vented cap, which means you can throw it in your purse with no worries. I love the Slim because oldest child wears braces, so he has to brush often. This brush allows him to carry it along in his backpack or gymbag without worries.
