I was one of the lucky ones with my Cloupor DNA 30 clone. I've had it for months and it still works great. It was my go to mod until I recently got a Sigelei 100w Plus and I still use it daily. Many others had lots of issues with theirs, so I'd suggest going with something else, like an iStick 30w or an IPV mini. You may not be as lucky as I've been with my Cloupor.
