At the risk of sounding like an Amazon shill, I like using Amazon when I can (I am also a prime member) mostly because of their no-hassle return policy.
I am sure some of the people here have to think I am a shill. After all, that is where I get my LG
batteries(from a 3rd party seller i trust on amazon), PG, VG, and syringes. I don't trust going through amazon for my VTC4
batteries or mods/atomizers, though.
Not gonna lie, I had one battery out of a pack of 4 HE4s that was dented just ever so slightly(see picture at end of post). I contacted amazon to see what they could do about it. They didn't ask for pictures or anything. They just told me to please dispose of it in a proper manner and they would send me another. I expected them to send a replacement battery. Nope. They ended up sending me another pack of 4
batteries. I ended up trying to use the dented one, and it has been fine. I havent tried it at anything over 40w in my sigelei 150w, though. Even though it is working fine, I don't want to push it too hard.
