I bought one of these to try. I wanted to illuminate a jar placed in a shallow recess in my garden in complete darkness. The brightness was so low that I could barely make out the jar. The light lasted for five nights and then it was over. It went in the trash! I didn't even want to return it. Most likely, it is not waterproof.

It is not worth it.... It has very low lighting.

I have 8 of these lights and I bought them for outdoor use. It has a sensor to turn on only when it's dark, it has a quality construction and it matches the aesthetics of the space I installed it in (terrace with gray deck tiles). They are resistant to rain (a lot of rain!!) and if I was worried about them, they work perfectly fine. I bought them as a test because I wanted something cheap, and I believe it's worth every penny and more. If I need more, I will prefer the same product again.
