I've been getting the same "no atomizer" message from my iSticks, too. It's more than likely the center pin on the battery that got pushed down too far and needs to be pulled up so it connects with the atomizer in the tank. An easy fix.
This vid is for an eGo battery but the principle is the same. Be very careful and slow when you're pushing on the center pin to pull it up, you don't want to pull it out.
You don't sound needy, you sound like a new vaper who needs some help locating things he's not familiar with. We've all been there. It's good that you're asking questions and not running to eBay, which is not a good place to go, imo. It's all too easy to get knock offs there and you don't know it until it's too late. We see the aftermath of this all the time on the forum.
These are basically Spinners and new. They're just prettier than the regular Spinners is all but still great workhorses. I think they just prettied up the original Spinners and gave them a different name.
You're in luck that they're even lower than before!
Vision USB charger: https://www.vaportalk.com/shop/vision-ecig-rapid-charger/
These are out of stock right now but waiting to get one won't hurt you because you already have a charger. It usually doesn't take very long to restock anyway. They should have them soon.
You can also use the Joyetech charger, they work just as well: https://www.vaportalk.com/shop/joyetech-510510t-usb-charger/
In my book, these are a must. I love to keep my computers in one piece, and there's a safety overcharge protection built into the adapters for extra protection.
Pro Tank 3 mini: https://www.vaportalk.com/shop/pro-tank-3-mini/
These will be around the same diameter as the battery you have now as well as the Spinners.
KPT2 or Kanger Pro Tank 2: https://www.vaportalk.com/shop/pro-tank-2/
These are the full sized tanks and will make your battery and tank combo look a little top heavy (lollypop), but holds more juice. You can use the Aerotank airflow controller on the full sized tanks: https://www.vaportalk.com/shop/kanger-airflow-control-valve-for-protank-protank-2-protank-3-and-aerotank/
These are the long stemmed replacement coils for the KPT2 and KPT3 mini. Even though the KPT3 mini comes with a dual coil, you can use the single coils with no problems: https://www.vaportalk.com/shop/pro-aero-tank-refill-dual-coils/
You can also use the short stemmed coils. These are what originally came out for the KPTs and then Kanger changed them to long stem. Some people report leaking on the short stem, I haven't had this problem except with a couple of them. Quality control isn't a priority with Chinese manufacturers so you will get a dud from time to time. https://www.vaportalk.com/shop/kanger-short-stem-pro-tank-coils/
I would go with a 1.5 ohm or 1.8 ohm coil in either of the links above. My personal preference is the 1.8 ohm because I find that it works with the widest range of juices. The 1.5 ohm runs a little hotter than I like, but that's just me.
If I forgot something, let me know. Right now, since you're on a budget, these are the things I'd recommend. Later on, you may want to look at an Aspire Nautilus or Nautilus mini with the vertical coil but those are around $24 - $26 and the coils cost more to replace. The KPT tanks are solid performers. They do have a Pyrex glass tank so you'll want to be a little careful not to break them. There is replacement glass available, though. With glass tanks you don't have to worry about what juice you're using. There are some that are known as tank crackers: heavy on citrus, mint, menthol, heavy on cinnamon... Plastic tanks are prone to crack with some of these. Glass tanks are not.
That's enough to get you started. Man, can you imagine the commission I could get if I actually worked for the VT store and not just a satisfied customer?
