No problems with this.

23rd March 2018 - April Van Hoorelbeke

Takes a full and fast charge

16th March 2018 - Jim Stewart

They have never gave me any problems and the price is way cheaper than buying them in a store. Good quality for a low price. Would definitely recommend if you go through batteries a lot.

7th February 2018 - Hannah Pate

I use these batteries in my Alien 220 and my T-Priv 220 Mods, and they work wonderfully. At 50 to 75 watts, I can get a full day's use out of them easy. I have 4 of these batteries, I have one pair in the mod, and one pair in the charger. I find myself swapping them out every other day or so. Very good batteries for sub ohm vapers!

it fits perfect on my vape

Hold a charge and haven't blown up yet.

6th July 2017 - Nicolis D Cothran

It's a rechargeable battery and you need them to use your vape. Samsung always makes really good products, so I have nothing bad to say about this battery.

1st July 2017 - Keith Partin

Safest and most reliable batter I have ever used. Holds a charge for a good amount of time
