I'm looking for advice on a disposable e cigarette to be used for thc oil. What should I be looking for? What type of coil, what temperature, etc. My goal is to not have to blindly buy a handfull and need test each one of them without first narrowing down the pool of options. To clarify, I'm looking to use a device that is approximately the same size as a cigarette and is disposable. Sorry if this information has already been posted, I wasn't able to find it! Thanks for any and all advice.
