I've been using the ego batteries, clones likely and the Kanger T3S for awhile and they work decent, but the T3S tend to break, usually after I drop them
They also are rather long in the pocket. I've used the box mods and many other things over the past 5 years and find the simple stuff is best. I always have the thing in my pocket and pretty much chain vape all day. Just looking for something simple that does the job and won't leak all over the place. Inexpensive as well as these things never seem to last all that long. Is the EGO ONE a good choice?
