Greetings from Malaysia and welcome to the crowd. I have been dappling since April and made the full switch around 4 weeks ago. It is sooooo much easier than quitting the 'normal way'. I started on an istick and
nautilus and it's still my best and most reliable set-up. The
subox kit sounds similar in many ways - but as some people said, more flexible, so you picked a great starter kit, which you won't need to upgrade anytime soon.
I know that Singapore is a difficult place to get stock from, so hope you visit Malaysia on a regular basis. We have some great vape-shops where you can try dozens of liquids to find out what you like. Good luck and dont be afraid to reach out here. People are really amazing!
