Well are they? What is a really good brand to get my first pen type from? They all look pretty much the same to me.
Snubber--the problem is that these all are rebranded and sold with different names like--Classic, Rio, Penstyle--Etc. So you have to find which on yours is. For example VaporNine sells an RN4072 that is called a Rio and it is the same as others with different names like njoy. If you need parts and someone is out of stock, then you need to hunt around to find a compatable part--I hope that explains it--Sun
