Initially very good (for about 1.5 years), until... it exploded.
The battery BURST and flew into the air, hitting the opposite wall and making a noise like a gunshot.

Very good, small, but it illuminates well, and it also has a ready plug, so you can move it wherever you want. I don't have an opinion yet about its durability over time.

Because it has not yet been necessary to operate in a power outage situation and as a new material in use, I have not evaluated its long-term durability.
However, at first contact, it shows that it is worth its money, although I expected it to be slightly larger in size and slightly heavier, thus with larger batteries.
We shall see!

I will come back for additional information after several power outages due to natural elements.
It has proven to be a rock of reliability despite its price and size.
Highly recommended!
