Congrats on 3 days!!!!
I didn't, but many many folks on here started out wanting something that looked like a cig and was easy. Most all of them were happy with that set up for about 5 minutes. As 18650 said, you won't find many fans of blu's, mostly because they are so overpriced, and they really don't satisfy folks for very long. For about 45.00 I highly recommend the kgo kit. It really is just as simple, and not much bigger. Mash a button, draw on it, inhale, exhale. If you are fine with the filler cartos, you can find them cheaply and the biggest issue will be finding juices you like, but you will have a huge selection to choose from. Or...buy blu flavors from Johnson creek or whoever it is. Approx 25 drops will fill a carto, when it tastes dry, add some more. Other than a tiny bit of size, the only real difference is mashing a button and dripping out drops from a dripper bottle.
Benefits:
510 thread connection that will allow you to use all the most popular types of juice holders out there
1100 mah battery = it will last you ALL day without recharging unless you literally never stop vaping all day.
Much less expensive!! Particularly in the long run.
Better ability to customize your juices: flavor, all vg, or pg/vg ratio etc because the cartos are so much cheaper, that you can have a lot of them on hand. 50 of them for 60.00 or 15 for 20.00 approx. The cartomizer is the what blu calls a cartridge, same thing.
Totally up to you, if blu is what you want....go for it. I just wanted to share some info that I've heard over and over and over from folks who started with those.
When I say slight size difference......the 1100 mah kgo battery with a regular cartomizer on it is about 1-1/4" longer than a cigarette and not much bigger around. Add 3/4" if you want to use a drip tip which I highly recommend.
