Man, I can't stand that type of solder sucker. The bulb doesn't provide enough suction and you end up with a really large, awkward, hot item.
I have used these for the last 5 or so years, and you can heat up the joint, lift the iron off, then suck the solder away. On some things, it can be really easy to heat one side of the joint and suck the solder away on the other. When the tip wears out, you can get replacements inexpensively.
