GreenSound GS Ego II 3200 mAh Quality Battery E Cig Rechargeable Pen Batteries (Red)

I have now ordered several of these. The battery lasts for 2/3 days after each charging, and seems very robust. A good solid feel in the hand. I wouldn't want to be without one and now have 5. This is the best brand I've come across. Used with my favourite GS atomizer, I'm all set.

Ecxellant pen! Would purchase again and recommend to family and friends! Lasts a full day charge, cant go wrong!!! Very happy!!!

Bought for gift and works well with plenty of power, but the placement of the button in a recess means it's not as easy to access.

Bought this product many times as it seems to be the only place that sells this type of battery.This is the worst battery yet, only lasts 1 day before it dies after 1 week of having the item, previous purchases have lasted at least a day and half sometimes 2 days.Not impressed

I have been using this seller for almost two yrs now delivery is speedy products are well worth the money and on the one occasion I had a faulty product it was refunded with no problem recommend both product and the seller

I've ordered 4! I'm so delighted, great company, great product!

Delivered the very next day.Right colours ordered and you get every thing the write up says.I have used this seller loads of times and never had a problem.

I bought two of these at the end of August. Both worked well and were an improvement on the ones I'd been using previously.Upon pressing, the button lights up white when fully charged, changes to blue when at about 50%, then red when it needs recharging. The battery would last a couple of days before requiring a recharge.However, after four months, the thread went on BOTH batteries within a week of each other and I can no longer screw in an atomiser.At £10 per battery, I expected them to last longer.Great while they lasted, but overall very disappointed.
