### ⭐⭐⭐⭐⭐ 6-Month Review

It's been 6 months and no issues.

### ⭐⭐⭐⭐⭐ Super fast shipping, great price, great product.

These batteries store a TON of energy. I use in my RC transmitters and they last all day long!

### ⭐⭐⭐⭐⭐ Great Value
*by J***5 on June 5, 2024*

This was a great deal for what is proving to be a great pair of batteries. I bought these to replace the batteries for my vape mod. After a full charge, I’m finding that they will last me all day before needing a recharge. It beats having to carry a charge cable with me everywhere. I’ll be returning for more when it’s time to replace these.
