Yep, simple as that
You might want a drip tip or two if you don't already have some. You can always use the blank cartridge that comes in most attys as a mouthpiece, but you'd have to take it out each time you need to drip
There is a little learning curve regarding how much to drip and how often, but you'll get the hang of it pretty quickly. Start off with a few drops and let it sit for a second, there should be just a slight gurgle when you pull on it, if you over fill it will seep out the connector end a little. When you first start out, keep a tissue handy until you get a feel for it. That way if you drip too much you'll be able to wipe up the excess before it makes a mess ;-)
