Query: Useless

I bought these lights for the back of an under the stairs closet. They were not very bright, but it was better than nothing. The sticky tape was useless. Both lights fell down within a day or so. I lost track of one of them, but found the other one and put it back up with some better adhesive. The screws they provided would have worked as well, but then the light stopped working all together. I finally got around to changing the batteries and found that the cheap batteries it came with had exploded and rusted out. (the closet isn't damp). New fresh batteries didn't help. Maybe the miniature light bulb is broken as well. I'm not sure and I don't care! I'm going to try a different product from another company.
