I do not believe the description mentions that the light flickers but I read that it does in a review and that doesn’t bother me. It’s not real big but I checked the measurements before buying so was not surprised. Suits my purpose. All you have to do is insert batteries. I placed it in my bedroom. Got delivered in a reasonable time so good buy. The only thing which isn’t much I always have to o turn it upside down to hunt for the onoff switch. But not a biggie.
