Pretty good. I moved from SplashID! to wallet thanks to MacHeist. SplashID!'s interface was getting old but that of Wallet is pretty slick.
The use is very intuitive and (so far) I didn't have to face the "password" issue mentioned in the other posts.
There is just a tiny problem when importing data, if the imported values have more fields than the current database allows the extra values are floating around and you need to fiddle with "edit", "lock", and add and remove fields until you succeed to move the extra bits around.
