## Customer Reviews

### ⭐⭐⭐⭐⭐ I am surprised
*by A***Y on September 9, 2024*

Giving these 5 stars after a week or so of using them. I am using them in a box mod, running at around 60w on a dual coil RDA. If you know, you know. They last just about a day (I put them in the charger at night, run a different pair of similar rated for the night and swap these in in the morningish time). I will update if they die early but they seem to charge at 1 amp pretty quickly, they're usually around 3.50v when I put them in, couple hours later they're at 4.2v. Happy so far.

### ⭐⭐⭐⭐⭐ Good investment
*by M***D on April 27, 2025*

There are quality batteries they seem to hold a. Charge well and it lasts a long time. I feel like it was a good purchase!

### ⭐⭐⭐⭐ These seem to be one of the better ones.
*by B***E on October 21, 2024*

Not perfect, like the rest I've bought, the first charge works for a couple days, then kinda goes meh. I like AWT's much better. They hold a good charge longer.
