half-size
I might change my mind over time so I'll update if it changes. The concern I have is for the connection to fail but at this time being brand new the plastic is strong, it's more polished than others I've used, the points sticking out are curved and uniform others offer two types with a round and a more pointed end for pressure points.<br />To me the obvious highlight and benefit of this one over others is the ability to downsize it so for that reason I think it will be great to travel with and easier to store. I'm giving it as a gift but I used it a bit first. I'll be asking them how it works out of course.
