This purse hook is a nice idea and very handy.  I dislike putting my purse on the floor of a restaurant.  Sometimes you can hang a purse on the back of a chair, but if the chair has a rounded back, the handbag often falls on the floor.

With this handy gadget, you can hang your purse right off the table, and often in a place where it is not in the way, but still safe (from someone walking by and grabbing it).

I just keep it in a pocket inside my purse, but you can hang it on the purse handle.

I recommend using a purse hook, especially now days that so many people have expensive leather or pricey designer fabric bags.  Also, there are new styles with double handles, which are shorter and harder to hang off the back of a chair.  With the Purse Hook, that is not a problem.
