Mine arrived 2 days ago. Definately a different sensation in brushing than my 5000. Feels more complete due to the larger brush head covering more teeth than Oral B but I would say my 5000 can polish the individual teeth more precisely becus of the smaller flexible brush head. Guess there is a tradeoff, don't know which is really better but this deal won me over, more accessories than the 5000, lithium battery, and overseas use since it conforms to the 220V standard. I just ordered the clone diamondclean heads from Ali so hopefully replacement brush heads are not a costly factor. We will see. The stanitation gizmo is just a gimmick, wish they had a timer display like the 5000 to c how long I brushed etc.
