Welcome , and there probably is , but being pre-setup , is no guaranty of them working properly . I bought a RBA , that had a wick and coil pre-installed , but the coil was shorted , and fried the PV, I put it on . So a word to the wise , test it with a meter first . You might want to start out with a clearo , of some kind , first . And they are easy to re-wick/coil .
