The free version is a nagware. It shows the nag screen every two files you open. The best part of it, it's placed on top of all windows, "Register Later" button is disabled for 10 seconds where closing and reopening iZip or clicking "Register Now" then focus back to iZip is definitely faster.
Do not buy iZip. For the same price of BetterZip ($25), why you would want this inferior product?
