Worth the low cost because it can be extremely helpful.
Very erratic - sometimes just will not work at all for no apparent reason. It usually manages to fail just when I need it most. It has got better at responding at each new version, but still fails sometimes.
Apart from sometimes not responding when called up, at other times, if you hold down the Option key a mite too long while executing an action, it pops up and gets in the way momentarily - but that is not really its fault. Nevertheless can be very useful from time to time or when learning a new program. Worth the money.
