excellent, light weight book light with good adjustability.  I gave it 4 stars because it's almost TOO bright and sometimes bothers my husband when he's trying to sleep in the same bed next to me.  I ordered the Kotek led lamp next because it has 3 settings AND a USB charger.  But it's bigger than the Mighty bright and a bit heavier as well.  So the MB will be packed when I travel.  Both good little lamps.
