I strongly recommend this purchase and here are the reasons. In the leaflet, it is said that once closed the shuttle can not be reopened .... well. But when they will arrive already closed in the package ... so they are useless! And this is not one that is concerned but 6 of 8! plus it seems that in view of their apparent fragility it is very difficult to implement. Product enticing by advertising but ...... this is its only attraction.
