You chuck the whole atomizer, but they last for months. I've never thrown one out, actually. I only use them for trying out new juices these days, but dripping into an HH 357 use to be my main vape.
If you are looking to do a lot of dripping, a rda might be a good idea. But, if you just want a way to taste new flavors or switch flavors easily I would go with the HH 357.
