Just to add to the topic. Welcome to ECF! I wish I has found this forum before I started buying stuff in September. I too made the mistake of buying discount smoke disposable ecigs. They almost ruined my impression of vaping.
I've quickly discovered that vaping is almost a hobby because you're going to spend a lot of time doing trial and error at the beginning. I'm a month into my vaping journey and finally found the setup and juices I prefer.
Try the Blu, order something like an ego-t, or even look at something like a Foxy Box Mod.
As soon as I quit worrying about my ecig looking like a regular smoke I quickly found what's right for me. I use an ego-t with the tanks on occasion, but typically end up using Boge 2.0 low resistance cartomizers instead. I also have a 5v Foxy Box Mod I got today that I use cartomizers with as well (standard resistance). I love both setups and each serve their own purpose. My fav juice all come from Vermillion River and my menthol juices from Mister E-Liquid.
Don't be afraid to try things and try different juice makers. Find your own favorites.
Expect to spend some money at first trying to find your flavors and equipment. Once you do the vaping adventure will be more cost-effective. 
Good luck with your journey and we are glad to have you here!!
