This device is an ohm reader, battery voltage meter, and has the ability to fire coils, allowing you to pulse your build and eliminate hot spots all while your deck is still on the meter, securely on your table. An ohm reader is an essential item to have, and for a rebuilder, you'll never know how you lived without one of these 521 TABs.  The ability to fire on the meter is incredibly useful.

My Take: Simply essential. It really is. You won't know how you're average meter sufficed until you grab one of these guys. You can have your atty ready to go without having to put it on a mod to dry burn. The battery voltage clips make it provide the essential parts of a Multi Meter for a vaper, and the ability to fire from a mech mod with the attachment is great. Seeing your live voltage drop is very important for some.
