I recently became aware that there are two versions of the mini. The DSE-901 and the RN-4075. There are a couple of ways to tell the difference:
1- cartridge has a slit for an air hole - 901
cartridge has a hole for an air hole - 4075
2 - atomizer heating element is long and pointy - 901
atomizer heating element is broad - 4075
3 - serial number on sensor tip of battery has "SLB" - 901
serial number on sensor tip of battery starts with "SH0" - 4075
It has been my experience that a 4075 is much better both in quality of manufacturing, but also vapor production and battery life.
If you know of any other differences or opinions please add to this thread.
