Great customer service from a real small business

My package got lost by USPS. I sent an email to the owner. The owner responded the same day. The next day he called to explain all the hoops he had jumped through to try and find my package. He did could not find it. Instead he shipped me out a new package that I received in 48 hrs. Small businesses are hurting right now. I do not know this guy from Adam, but I do know Josh is exactly the kind of small business owner I want to support right now. Thanks Josh you are running a first class shop.

Great Product

I see Samsung is doing their "do not vape using or battery" campaign. Anyone who vapes knows these batteries are the best. We all know they aren't designed for vaping but they're still the best!

Great Product

The 25R is by far my favorite battery. Samsung is wanting to get away from their batteries in vape units so they put "Not for e-cig's and vapes" but they are still the best around. 100% recommend.

Fast and easy

This was hands down the easiest experience I've had, but why do they state "not for e-cigs and vapes"?

Hassle free/easy experience

Batteries work great and got them way cheaper than my local vape shop and better quality of batteries for sure.
