This has made a good pod mod into a great pod mod. I have never been a big fan of coils, and the .4 ohm coil uses a lot of juice. This RBA has made a big difference to me. It has a great design in my eyes, just unscrew the cap and your straight to the coil for easy wick or coil replacement. Like all RBA's it's only as good as the coils you put in though, i have found 2 mm ID works best for me to get a good loose MTL style draw that suits me down to the ground.It has made me a happy chappy.
