Great notification Widget

Like the new look from update from Rocky SandStudio. Everything seems to be added to side controll panel no more Dashboard widgets for me this is the future look for desktop it seems with Battery Monitor leading the way. No Bugs! No glitches! just sleek streamlined info about Battery health and cycles and temperature along with source of power all in a row in notification center

Low Battery Alert Doesn’t Work

I like this app very much. The recent update brought another useful feature; low battery alerts. But I don’t get any alert for low battery whatsoever, even the notification has been enabled in System Preferences. A bug?

This really wrinkles my sprinkles. In a good way.

I really like this app. There is a lot of useful information to be displayed and it has a very good look to it. What is there not to like?
