Bests & Worsts Reviews from Amazon

I'm baffled by the negative reviews. (e.g., "batteries don't last long." Um, buy better batteries? The batteries don't come with this item. "Kept falling off." They come with screws for adhering. Or get stickier stickers.) I've had none if these problems, so I'm diagnosing user error. For me, these are better than any other for illuminating under shelves, in closets. (Yes, they are not very bright, but bright enough.) I especially like that they are unobtrusive, easy to stick up, and mostly the ease of on/off! I just swipe my fingers and voila! I've tossed all other that needed tapping -- though you can tap these as well as swipe -- and ordered these in bulk. Price is nice too.
