They are for me. I've used regular atomizers with the refillable cartridges, dripped and sometimes even sipped. Used regular 510's and 901's gave the 801's a shot long ago and then I found Cartomizers / Atomz.
I can fill a few carts and go all day @ 3.7v on a single cart. At 5v I have to refill or top off the cart every few hours with 10 or so drops to keep them wet.
I get 30+ drops in an empty and roughly 10 - 20 in a refill.
I take a couple of batts and a few carts with me and I'm good for a 2 day road trip easily. I also carry a 3ml bottle of whatever flavor is in the carts for quick refills.
For traveling and sitting in an office they work for me.
If you're a dripper, you enjoy it and your lifestyle allows that then maybe they aren't for you. But I'm really impressed with the fact that I'm not having to constantly drip, super low maintenance, and the performance I get from the Atomz/cartomizers.
vaping is such a personal thing and it depends on what your use to and how you like to do it. There's a learning curve with the Atomz so you don't burn them, keep them wet, etc like any other form of
vaping.
