+1 on the isticks for a battery paired with a nautilus tank. I wish these were out when I started vaping. Especially for the price and the quality of vape you get compared to say an Evod. One thing to consider is look for a vendor with great CS and a warranty/return policy in case you have a issue. Although the isticks I own now work great (a 30W and a 50W), both went back to the vendor and were replaced for various QC issues. I was probably just unlucky on mine but something to keep in mind.
