has held only a few weeks

I bought the castle for our child bike seat (Romans Jockey Relax) to connect it to the bicycle frame. At first I was very pleased, the three-digit code could be easily adjusted to handle with red and black button not too complicated.

The castle was very little open in the next few weeks, only when we have removed the seat once a week by bike, we made it up and then back to.

After a few weeks the lock jammed from time to time and opened up, although I had actually completed. Then it went on during the trip, when my son was playing with it. And last we lost it.

I am still looking for an alternative, this castle it will probably no longer be. As I had expected more Abus.
