Congrats on buying a kit (I assume this is your first e-cig?) and making a good choice of seller, too.

Only been a month for me, and ECF & ElectroNicStix was a great way to start.
(If you're totally new to the forum and to e-cigs, I highly recommend DonDaBoomVape's
Wonderful World of Vaping intro.)
Jason will probably have some good input for you, but this is just my view on the cartridge issue you're having:
For a too-dry filler, you can buy extra
juice (a good idea in any case!) and add it to a pre-filled cart or try dripping 1-2 drops of
juice straight on the atomizer bridge (not too much or you'll flood the atomizer). You'll get a burnt taste when the atomizer is starved for
juice.
You might have gotten some that are a bit dry, or you could be having a standard problem people often have with the polyfill cartridge filler material (i.e. slow and poor wicking ability).
You're dealing with the factory-made pre-filled carts (the Marlbro High) that we (almost) all started with on the 510. (They are the standard for the 510 starter kits, so you'll get them from almost any seller.) Some people like them fine, others switch over right away to one of a
gazillion alternatives.
And this is
purely my nearly-still-a-noob opinion...
...but I think the cartridge filler is the weakest link in what is otherwise a very clever and sleek design by Joye. The polyfill is not that great as a material, and almost nobody seems to get those factory carts to last as long as a pack of cigarettes. Don't judge e-cigs by those carts, in other words, if you don't like them.

Here's
one discussion on dripping (i.e. putting 1-2 drops directly on the atomizer bridge) and cartridge troubleshooting, for instance. You can always ask for input from Ask The Experts or the New Members' Forum (you can't start a new thread elsewhere til you reach 15 posts). You'll find
plenty of discussions here on the best way to get a 510 (or any model) to work well, but really once you get past the learning curve and find a way that works for you it's not that much of a hassle.
Personally I use dripping and the
blue foam filler...but everyone finds their preferred method.
