I think this a a fine product ... very easy to set up and works well.  I gave it four stars only because I don't "love" it (that's the 5 star standard) and I wish the light were a bit brighter.  Yet it certainly does the job and is bright enough to catch one's attention even if in peripheral field of vision.  Probably not bright enough to attract attention if one's back is turned unless the room were dimly lit.
Rating: 4 stars
