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.

2 of 5 Why did I buy this? July 17, 2018
Reviewer: DarthVapor831 from Watsonville, CA United States  
As a new builder you read a lot about safety. I was concerned enough by what I had read that I purchased this Coil Master 521 Tab unit, which I've owned for a few months now. I will say I have used this meter successfully zero times, yes zero times. Why you ask? Because it only measures resistances that are greater than 1ohm, which with all of my RDA's and rebuild-able tanks are rather small to accommodate. So perhaps it is a great unit for what it does, but it does me no good at all. Also with regulated devices (like what I use) a meter like this is absolutely unnecessary.
