The Triumph consists of two main parts, the brush handle with brush head and the wireless SmartGuide unit. The handle communicates with the SmartGuide to relay information on which of four pre-programmed brush actions you're using, how much time has elapsed since you started and which area of your mouth you should be cleaning. It also gives you a visual (but not audible) warning if you're brushing too hard and will advise you when each brush head needs replacing. Two brushes are included in the package, one a FlossAction for everyday use, and the other a ProBright for occasional polishing; inserting one of them into the handle will automatically select the appropriate brush action, which is then displayed on the SmartGuide unit.
Electric toothbrushes do take some getting used to if you've only ever had manual brushes but once you get into a routine the whole experience does leave your teeth feeling cleaner and with less chance of causing damage to your gums than a conventional brush. The brush gives around an hour of total use from a 12 hour charge and the whole thing (handle as well) is waterproof, which makes cleaning after use much easier than older brushes - you just run it under a tap and wipe it dry on a towel. You also get a travel case included so can take the brush with you on holiday. I would add that the handle is a little heavy and somewhat ungainly in the hand at first, whilst the placing of the buttons makes them a bit easy to press in the middle of a clean, so changing the action just when you don't want it.
The SmartGuide itself is a nice inclusion that does look good and gives some useful information, although if I'm brutally honest it's by no means an indispensable addition. It isn't illuminated, which could be an annoyance if you have a poorly lit bathroom, and it can be a bit of a pain to keep it in view when brushing so I find myself not looking at it which kind of defeats the purpose of having it. The handle vibrates slightly at given intervals while you brush to advise you on timing and I tend to use this rather than the timer shown on the SmartGuide.
Like all Oral B toothbrushes, this one cleans well and should last a long time of use. The SmartGuide is a nice but not essential inclusion and replacement brush heads are pretty expensive, but you do seem to get quite a lot for your money with this package. If you like electric toothbrushes then you'll really like this one; if you've yet to try one but the price is putting you off then maybe consider going for a cheaper oral B brush or the Triumph without the SmartGuide as I doubt you'd miss it too much.
