I prefer them if I'm going to use the tube style mechanical
mods. I like the size of them better and it doesn't feel like I'm holding a sharpie.
Why I switched to Reo's. It's bottomfed so I don't have to carry a bottle around and drip every 4-5 pulls. I just squonk the bottle and the
juice goes through the bottom of the atty. It's more convenient.
