NICE

### ⭐⭐⭐⭐⭐ Great customer service
*by C***R on July 8, 2022*

I ordered this exact set twice. First time was 2 years ago, the two batteries that came then still work great! The second set I bought in June, they were functional until I tried to charge them, they are both no longer responsive. Contacted customer service but they weren't any help.**Edit customer service contacted me again. Michle Smith, thank you for taking my concerns into consideration. I did not want replacement batteries, I want these repaired. They refunded half the cost which I will use to hopefully repair them. BMS boards aren't really expensive, so as long as the cells are good I should have a couple batteries. Yeah I put in some extra work, but it's kinda fun, ya know?I hate to leave the OG review, but maybe there is something up with the design. The two sets of batteries I have use different BMS boards, failed design change maybe?Good luck!

### ⭐⭐⭐⭐ Good batteries untill this happened...
*by M***L on December 1, 2020*

Bought these batteries for use in my Milwaukee leaf blower this fall. I found that one battery got super hot and smelled of burnt plastic after 5 minutes of use. Come to find out that it got so hot that it melted one of the terminals in the battery. Cant find any info on how to warranty the product since its 7 months old.Edit: the company reached out to me and sent a replacement. They new one seems to be holding up. If your looking for a battery in a drill then these should work. Any continuous load like a leaf blower they will overheat very quickly.
