I like the idea of these mod box covers. Looks very cool with a splinter and wood stem.
However do you have to remove the splinter to access the battery? The 510 connectors are rubbish on these mods. Personally i would only use joytech mods if you dont plan swap the atty. Best to have one atty per mod. Taking the splinter on and off is a big no no on these cheap mods.
After a few swaps my cuboid showed problems measuring resistance. Would not buy one again myself.
@KeroZen also has reported similar.
My advice when buying a mod - look at the 510 connector first!
P.S. very happy with my slightly more expensive smoant cylon.
