I think all the devices that use removable batteries are big for little hands. Doesn't matter if it's a ProVari, Vamo or something else. Even the box mods are big for my hands. Also, having arthritis doesn't help. Having said this, I use my ProVari daily. I use eGo type batteries when I'm out of the house and will continue to use them as they are easy to carry without having to get a bigger purse.
