Been thinking of buying Indulgence V3 for a long time now. From the looks of it, it's not actually upgraded, it's downgraded. The small cone is not even included in the kit. It looked like it's built with cheap metal and the design is not as attractive as V2. I don't own the earlier version. I've only seen it in videos. First of all, are the V2 parts compatible with it like the V2 18350 sleeve so I can use a shorter version of it? What about other V2 accessories? This is not clear in many sites carrying the mod.
