I bought two, one. For my car, one as a gift for my father I am of the opinion that such a tool should be part of any car equipment such as first aid kit and warning triangle. However, not buried in the trunk, but in the storage compartment in the center console, where you rankommt definitely, even if one is upside down in the ditch.
From everything works as described, can I fortunately (!) Here does not say, but it all looks very robust and high quality, is very well in hand, and I have no doubt that it will work (like everything I far from the house of Victorinox in hand had).
In my eyes there is plenty lifesaving aid for moderate price.
