I use the new Aventflaschen and had previously tried various brushes. Mausche are simply fallen apart, right in the first time. Others were flattened fairly quickly and everyone was kept impractical. With this brush, I'm really happy! The bristles are very stable and the small brush with suction cup including that one can beautifully pure screw in the style of the brush fits perfectly in the vacuum cleaner. The suction cup holds super at the edge of the sink and is thus always at hand, yet never in the way. Fine part that is worth its price!
