I'm old school and love my Silver Bullet. There's nothing that compares to it in my opinion. It can be ran over with a truck and still vape away like a champ. Combine it with a Protank 2 or 3 and you have a great mod. I own two, one black and one white. I use it at 6 volts and 3.7. I used to take it with me when I was out and about but found that the EGO battery was easier to carry. When at home I never use an EGO except to test out new flavors on a lower voltage. The low resistance coils come in handy when vaping at 3.7. I can't remember when I had a 3.7 battery in my Silver Bullet since I bought the EGOs. It really is personal preference.

Sometimes you find a vape that tastes better at 6 volt and sometimes better at 3.7. I can always put a kick on my Silver Bullet if I want to try that sweet spot I hear everyone talking about. The kick lets you make your mod a variable volt.
