You rang?
First, congrats on your five year mark. I remember when you first came on to this forum... you've been missed lately.
I've been trying the pods lately. Like you, I'm tired of lugging around a fist sized brick although I do still use them at home.
The first pod I've tried is Vapor Talk's Amethyst with the nic salt pods. I'm in love with the size, it's perfect for stealth vaping and so easy and light to carry around. The mixed berry flavor is amazing (the kit comes with four pods - menthol, tobacco, mango and mixed berries). That said, it's small -- something like a 250 mAh? and the pods are small so they don't last long. I could live with that - to a point, but the major downside to it is that many of the pods leak ( @Christopher said they can be refilled but Vapor Talk doesn't sell the liquid by itself, you have to buy the pods). When it leaks enough to get into the battery part, the battery stops working. Chris is aware and said they're working on it but for now, the leaking pods being so expensive ($12.99 for a 4-pack), it's not my favorite although it easily could be if they fix the leak and sell liquid by itself.
Bought the SV MiPod, it's a little square thing with a refillable 1 ml pod. You can refill 5 - 7 times before the coil goes out. Of course, if you're using sweeter, darker juices... you know the drill. While it's cute, I'm very disappointed in the little button (five clicks on/off), it never turns off and the vapor is hot. I've burned my lips a couple times already despite changing out the pods -- of course I bought extras! This one is a no for me.
The GhoSTick is another pen style refillable pod system. The pod holds 1.5 mls of liquid, 2.0 ohm coil, 350 mAh battery and comes with the charge cord and two empty pods. All the pods take a minimum 50/50 juice. Any more VG and the coil burns up faster, too much PG and the pods leak, which is what I think is the problem with the Amethyst pods, it's too high in PG. Anyway, this is the winner so far for me. It's got refillable pods, it's a little longer than I'd like, the Amethyst's length is perfect but you give up battery life for shortness. I've been using this one a lot lately and have bought some of my favorite juices in 50/50 at 12 mg regular nic (higher nic so I don't vape it as much).
I have a SMOK Infinix on its way with some extra empty pods, they should be here tomorrow. It's very similar to the Amethyst so we'll have to see how that one works.
If I were to recommend one of the ones I've tried, so far I'd say try the GhoSTick and mix some juice to 50/50 and give it a whirl.
