The Aegis X with the Cerberus tank is a powerful piece of kit. It's a cracking device but as others have said, get another mod kit or pod kit as a backup. You will fine different setups will give you different vape experiences.
I'd look at a pod mod kit as a back up and see what you think of it.
I'm using the Voopoo Argus pro pod mod and it's a lovely vape.
