1. Which? magazineDetails/Subscribe
In a test at Britain's Which? magazine, the Oral-B Triumph 9900 and 9500 (immediate predecessors to the SmartSeries 5000 and 4000, which share the same technology) are given the highest marks. Testers say that the toothbrushes are expensive but do an excellent job of cleaning and have an especially long battery life.

In this clinical study, the Oral-B Triumph removes more plaque than the Sonicare Elite 7300 electric toothbrushes. The study is sponsored by the Procter & Gamble Company, makers of Oral-B toothbrushes.

3. Consumer magazineDetails/Subscribe
Five staff members at New Zealand's Consumer magazine compare the Oral-B Triumph 9500, which is similar to the 9400 in the U.S., with their own powered toothbrushes. They find the Triumph more effective at cleaning and more comfortable to hold, but they also note greater vibration against their teeth. The Oral-B ProfessionalCare SmartSeries 4000 is the successor to the Triumph, and it employs the same technology.
