First off I just wanted to say hello to the community as I'm obviously a new member. So, hello! Alright, on to my recent purchase. I recently bought a Lavatube V1 from a co-worker, and so far I love it, but I do have some questions. I had seen a review video about it where someone pointed out that the tube doesn't actually have a vent at the bottom as the hole isn't drilled completely through. Is this something to worry about? Are there any precautions to take that I may not be aware of? And would it be smart to finish the drill hole into the chamber? Next, what is the best tank to use with something like this? I'm currently running a 2.1 ohm iClear 30. Is this a good tank to use, or should I look into purchasing something else? Also, as someone who still doesn't fully understand the differences between cartomizers, atomizers, and clearomizers, what are the pros and cons of each? And finally, what are some general tips and tricks to using ecig mods? I've only been vaping for a little less than a year, but exclusively with egos. Thanks in advance to anyone who took the time to read this, and I'm excited to take part in this community of like-minded people! Edit: I just checked and the hole is drilled completely through. Sorry I didn't check before posting, just ignore that bit.
