Important Note:
Rebuildable atomizer coils and wicks have known risks.

Rebuildables are for experts, not average or beginner vapers with no multimeter or knowledge of how to use a meter, or when a meter must be used, or how electronic devices work. These materials cannot safely be used by the inexperienced or those without basic knowledge of electronics.

This is because:

1. A rebuildable coil/wick MUST be tested carefully with a meter before it is used.
2. If it is not tested it is entirely the risk of the user.
3. Faulty wicks/coils WILL blow electronic devices.
4. New coil/wick units must be tested and then used first on a strong basic electrical APV that has short circuit protection.
5. No new coil/wick assembly should be used on an electronic device until known to be safe.
6. These items destroy electronic devices if faulty. This is a known issue.

JUNK September 12, 2018
Reviewer: Stephen  
It worked like it was supposed to. THREE TIMES. Then the 510 got loose. This product is glued together so you can not take off the bottom to tighten.
With that being said. I love this website and do not hold this against them. I did not contact them about this because I do not want a replacement.
My Vapor Store has great fast friendly customer service!

Works great August 17, 2018
Reviewer: Anonymous Person from Lancaster, PA United States  
I am not a fan about guessing on ohms or using a mod to test for shorts. This solves both problems.
Nice for test firing as well.
