What are the advantages and disadvantages of either Sigelei vs the IPV3. I am looking into a new box mod and can not decide which one to with. I am a heavy vapor. Most of my coils I build are .2 ohms or higher. I am thinking about going with the Sigelei for the simple fact of the magnets I hate messing with screws just takes unwanted time to put in new batteries. Usually vape around 55-65 watts. I have read several forums and watched videos and am having a very hard time deciding. Any help is great thanks!
