I have 2 clipas (gold and silver colors) and I feel that they are much better than many of the other pursehook designs that I have used in the past, because clipas are versatile and can be used in a variety of situations, not just on the edge of tables - I've used them on church pews, restroom doors, etc.
In the past I've only used them occassionally (but I was always happy that I had one with me when I needed it!) but lately I have been using them a lot.
This summer I've started taking the crowded commuter train into the city to work and I often use a clipa to hang my purse on the back of the seat directly in front of me. That gets it off my lap so that I can easily read, enjoy my cup of coffee and banana, etc. The rounded, padded clipa edges do not harm the vinyl seat covers at all.
They are heavy duty, too! Yesterday I used a clipa to suspend my fully-loaded Isabella Fiore leather bag that has solid brass hardware (one of my heaviest bags) and it was no problem! Go Clipa!
I see women dumping their bags on the filty floor of the commuter train all the time and it makes me ill!
