Not for use with car ignition keys!
It isn't clear from the description that these devices will NOT accommodate a typical car key.  I bought this for my mom, because she has arthritis and her ignition is difficult to turn (even for drivers without arthritis).  Most car keys have that thick black plastic &#34;head,&#34; and they do not fit in these key turners.  I think that should be explained clearly in the description.
