When it comes time to replace them, I've come across a couple that were bad from the start. I've also seen my Kanger aerotank mega, leak when I change altitude... normally it's a matter of taking the bottom off the tank, then putting it back together. I normally get a week out of the mega and a bit longer on my mini aerotanks.

My EVOD Mega had been leaking, and i was ganna trash it not knowing i just needed a new atomizer, lol. But long story short it hits like new now that i got this, ill be ordering more soon. Thanks for your business.

Very happy to find these. Will order again!

Only about 60% work outbof the box. But i have all kanger clearos,so im kinda stuck

I have phased out of all my tanks other than Kanger due to the availability and price of these coils. I've placed three orders of 15+ at a time and have yet to receive one DOA. They work great in my T3Ds, Protank 3, and Aerotank 2 V2. I really appreciate the fast shipping and great customer service too!!!

I have been very pleased with these. I believe I have only had a few that have not worked but for the most part, they have been very good.

Hoosier Cigs! Been using the Kanger dual coils for years, the middle of the road 1.5ohm! Dependable, along with Dekang juice and never ever had any issues! Best cool for the money:)

Great product. I use the V2 and it works well at a low price. Very quick delivery.

I have been using Hoosier E Cig for several year's and there staff is Super helpful and very noligable about different products and this were I get all my wicks and all my equipment as well?????????

Just what I needed, hard to find elsewhere, quick n easy ordering with a great price! Thanx so much!!

I've depended on these for my protank 3 for years. They never fail. Ive boiled them in water to clean them, and they still come out after drying firing right up. The ONLY choice in 510 pen tanks

I like the price of this product , but quality not so good . Sometimes it goes bed quickly .

I think u guys r great

Very easy to order and fast delivery. Thank you very much.

These are great. Sub Tanks are Awesome.
