All right man I know exactly what you mean.
My first pen battery was from Dr Ex and I still use it from time to time but I find the Ccell button less battery's better for me personally and had this argument with my mate as his view is a batter is a battery so who cares.
I got a Ccell one from SCL and really liked it but I also got a Silo from amazon which I really like and mostly use now. Highly recommended my friend!
Take it easy
