The cleaning sensation is pleasant, just as with the Precision Clean. The slanted bristles grab pleasant in the interdental spaces, but you'd just as well be possible with the Precision Clean, if you keep this somewhat oblique. For the CrossAction cleans not thoroughly the flat tooth surface as the Precision Clean. The same can not necessarily feel, but you see it (discoloration).
Basically, a good brush. If time is less time for cleaning, the CrossAction has its raison d'ĂȘtre, but in the long run it is not an alternative to the Precision Clean. Better than the significantly less cleaning and unpleasant Deep Cleaning Brush but it is all.
Nevertheless, with the price-performance ratio not buy recommendation.
