this philips hx9911/88 electric toothbrush is actually pretty solid. good for anyone who’s lazy with brushing or forgets how long to brush. works well after coffee in the morning or right before going out. connects to an app, so it's easy to track how well it's working. also comes in handy after big meals or when teeth feel gross after snacks. the extra brush heads mean no need to buy replacements for a while. battery lasts for days so perfect even for short trips.
