I know nothing about pods. Just a couple of questions, if you will be so kind.
Are they refillable?
How long do the pods and coils last?
Did the battery get you through the day?
Definitely refillable. Pods last damn near forever. Coils? Depends on what you're vaping. I've gotten 1-2 weeks on a custard based juice. Lighter ones that are more fruity should last longer.
Battery should last all day with normal use. Now if he's going around puffing and going "choo choo" all day long, might be good to have a backup stashed. I never wiped the battery out during the couple of years I used it.
It really is a nice little setup. Search for deals on coils and stock up on 'em. Otherwise, the actual rig itself is rather inexpensive.
Oh, and get a couple of extra pods. You can pre-fill them and swap out on the go.
