Good cartridge

this works great, it doesn't leak and it holds a good amount. i'm happy with the overall product.

Great price great product works just like any I have purchased in the store.

Outstanding tank easy to fill

I love how much nic salt these hold so I'm not constantly having to refill it. But it's soooo easy to fill that it wouldn't matter if I had to anyway. And every time I've come here to buy them they've been on sale! (which is what keeps me coming back lol)
