screw together clearo

[Beaverkt]

I am currently using mini vivi novas. While they are working fine i am interested in tryinh others. One big requirement is that they screw together. I tried one a good while back . I believe it was a stardust but i am not sure. Any ways the plastic tank part only press fit into the base. This came apart in my pocket leaking out all the juice. Ever since then i have only used the novas since tank screws in ensuring that it wont come apart in my pocket. So what other clearos screw together ?
