    Satisfied
  

*by T***E on Reviewed in the United States on August 21, 2018*

Needed a replacement for my geekvape ohm reader and this was perfect. Accurate readings combined with being able to dry fire any coil I’ve built make this one a winner.

    Gets the job done
  

*by M***Y on Reviewed in the United States on January 11, 2021*

Build quality is decent, but a bit flimsy.  Overall its good, just be careful putting on your RDA so its not too tight or you may risk having trouble getting it unscrewed from the reader and possibly breaking it.
