If you've never tried it before I suggest using something disposable for first try. Maybe a carto or dripping atty. I for sure wouldn't fill up a Reo with it until you know if you like it. And even then you are making a commitment. It's almost impossible to get the taste/smell out of whatever you put it in. I have a Reo dedicated to Pluid/MahaRa/Agent Orange they are all three very clingy and luckily for me they play well together. I go from one flavor to next without cleaning anything out. Sometimes I'll top off a half bottle of one flavor with another.
