Does what it says on the tin

It's a basic function generator but its digital display is what makes it perfect for lower frequency design. I haven't tried the Voltage controlled input yet, but I expect it to work well if judging by my initial work with it. I only give it 4 stars though as it doesn't mention in the description that there is a cable included therefore I bought one. Not an expensive mistake, but still a bit annoying that it wasn't made clear.
