1. When first mounting the eyelet for attaching the safety coupling pin is easily broken. The plastic is too hard and thus far too immobile.
2. Overall, the attached push rod makes in use rather a wobbly impression. The service life is yet to be assessed.
3. Height adjustment is expandable: People from 1,85m go anyway in a slightly stooped posture. Needs improvement.
Addendum to life:
Unfortunately, the push rod has less than 12 months survived (with winter break). Our second child needs support and we currently still unfortunately a new pushrod :-(
