Extremely happy with these.  Very sensitive to motion and wonderfully bright!  I had one just sitting on the counter after putting the batteries in and it turned on as my husband walked by.  I have not yet mounted them to any surface yet, so I'm not sure how well they will stick.  Planning to put one in our coat closet and the others under our kitchen cabinets.  Looking forward to not having to turn the hall light on every time I go in our coat closet.
