Cheap imitation

The brush heads are made of very cheap plastic. Grasp itself like pure chemistry China. The fit is also insufficient, the heads sit very loosely to the brush and fall while brushing just once from. The bristles themselves are partly just too long so protrude the einzellne bristles from the composite. For this purpose, they are partly sharp or sloping schnitkanten because I can hardly imagine, my teeth / gums something good to do.
Conclusion, bad investment! Dear but buy the original .. who buys cheap buys twice .. here is true the saying again!
