The board is easy to install and easy to use. Personally I withdraw (the fixings remain in place on the stroller) when I do not need because it tends to fall when I simply goes with lanyard (or so I do it very badly). It takes 1 minute and is less painful for the shins!
The board is comfortable and child in the place (even on the mini model). And you can really go up and down sidewalks worry (even very high). By cons, we must learn to walk not to take the foot in it and in terms of handling of the stroller that complicates things a bit. That said it's still better than a child who does not work ...
On a positive note we lost one of the screws. By contacting the French dealer Lascal (contact on the website), we were offered to return the spare part free.
We do not regret our purchase!
