### ⭐⭐⭐⭐⭐ Review
*by T***I on 30 January 2022*

My original battery was almost 3 years old, and was down to 20 minutes or less of runtime. This battery dropped in (clean all your contacts first - good electrical hygiene) and immediately started charging on the dock. I let it charge over night, and then ran the device and am pleased to report about 90 minutes of runtime. My device works like new again, for a very small investment.
