Can never fault these Samsungs - always have at least one spare set in my handbag at all times!!!
Great batteries, I charge my vape maybe every 4 days and it still has plenty of juice left even then. Definitely need to get a back up pack
It's a bit early to tell, but these seem to do the job they were designed for.
I've used these batteries in a number of mods and have received life from them. A good buy.
