The clearos are very easy to use. Just unscrew the top cap and fill her up. I think there are a perfect size for going out and about. Looks like you've been doing your research. You ordered a great kit ans Sweet-Vapes makes awesome juices. I recommend their Nutty Coffee and Green Applebacco.
I rushed home from work to find my Lavatube 2.0 waiting for me. Its beautiful. The size reminds me alot of the Silver Bullet. It is lighter than the SB. Ive only been using it for 5 minutes, so I cant give a review, but so far I am impressed.
Having used both now. I would choose the Vamo over the MVP. The MVP worked well but the batts are non replaceable and in the future when the batts go out, you basically have a useless box unless you tear it open and mod it. The Vamo also has better functions IMHO
The carts ( which are useless) are Marlboro flavored. I recommend getting one of these also http://www.theveteranvaper.com/ego-2-4ml-cc-long-wick-changeable-coil-clearomizer-clear/ and a bottle of your favorite juice.
The Vamo has an extension for using an 18650 or (2) 18350's. Without the extension it uses a single 18350. I've been using it all weekend and I am impressed with it. It is about an inch longer and is heavier than the Provari.
I should receive my Lvatube 2.0 tomorrow.
Preorder is $142.95.

It does sound like nic OD. Since you didnt smoke before I would recommend not even taking up vaping, but if thats what you choose I would recommend 0 nic juice.
