If I could return it and get the Dremel Brand than I would. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A Great Replacement or addition *by K***K on Reviewed in the United States πŸ‡ΊπŸ‡Έ on January 30, 2022* i wanted to add a 2nd battery to my arsenal for my Lithium Ion Dremel. I did the research, read the reviews. I decided on this one. i have used it a few times now and it charges rather quickly and seems to run longer than the stock one that came with the tool. it has plenty of power to spin up a 2 1/2" sawblade to 25,000 RPM and cuts through sheet rock like butter. i have finished working so far every time before i ran out of battery, so i don't know how long it will last, but i know i did a pretty steady hour of cutting with it. it anything changes i will update my review, so far I'm loving it. may get another one, cuz nothing is worse than having to stop and charge a battery mid project. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It works well!!! *by R***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on August 3, 2022* Needed accessory for my tools.
