At first they seem like a good deal didn't seem to last as long as the DeWalt but the build quality seems fine

Couldn't ask for better

4 for price of one dewalt. Battery life seems same as dewalt. Havent used much yet but impressed with them so far

They work fine.

I was very skeptical as to whether these were going to be garbage or not especially since it looks like I’m the first person to ever buy these from this seller lol I own many many dewalt tools and I use them all hard and daily (flooring contractor) and I also own a heated coat that uses these dewalt batteries. I intend to use 2 of these towards my drill/impact and the other 2 for my heated coat I use while hunting. My first thoughts when unboxing was wow, they smell like candy canes for some reason lol my second thought was oh they even have the button indicator on them like some of the better dewalt batteries do. They look identical to a dewalt, I did a side by side comparison. I have not used any on a tool yet but I have confidence in them. I can not speak for longevity on them but don’t forget that dewalt batteries are also made in China like these are and they only last about 3 years til I start noticing a major decline in power/run time. I believe these will perform similar.
