Hopsi fun, and it does matter.

We decided after many compare and a long search for the Hopsi Storchenmühle.
First, because Storchenmühle is a company with many years of experience and also attaches a certain sense of responsibility on the day. In addition, this product is Made in Germany.
,
Now for Hopsi:
The build quality is impeccable. The complete Hopsi is ready within minutes. It only needs to be a door frame available, here the clamping bracket requires a pad on the door frame of at least 5 mm and the door frame must not be wider than 30 cm. Fits in most cases, but it can in old buildings sometimes do not function.

At the doorway no damages take place, since the Door bouncer spans over a spring, and at the end of the clamp are soft rubber caps.

Our doorway has only 5mm and the Door bouncer keeps really bombproof.
After attaching the door frame should then only briefly to adjust the straps properly and ready.

Our daughter loves the Door bouncer and has the greatest fun with it. Even the seat is excellent padded.
However, at the beginning of the seat a little big, which is why we initially always placed a towel around his waist our daughter. This then stabilizes the seat of the child.
Important is of course also can keep your head really well the child, because there are indeed left and right of the seat, the belts, and if the child is shaking too much with the head then it may be that it scrubs sore. Alternatively helps here but (found in every car department or here on Amazon), a belt pad.

The times should be respected for health reasons, not longer than 20 min. And use only under supervision.

From me and my daughter, there is a strong buy recommendation, the the thing is super safe and great fun.
