Quality and Affordable Lithium Electric Toothbrush
This has 4 vibration modes Clean (normal), Sensitive, White, Gum Care, Soft.  In my pictures I compare the size to my Series 2 from Sonicare.  This VIOD cleans the same if not better.  It uses the same Brush Heads, so you can purchase generic replacements easily.  The Lithium batter charges better and last a lot longer than my Series 2 NiCD/NiMH.  Overall this is very high quality, better than I expected, and its 1/3 the price of my Sonicare.  Very happy with the purchase.
