These little lights are just right for reading at night without distubring my husband.  They also don't get hot like some others.  They clip on to the edge of a book of tablet case, etc. and are small enough that they are not always in your way.  The base is shaped so that it not only holds the batteries, but will sit flat on a table if needed.  However, because it doesn't "flatten out", it may be awkward to stuff into a travel case with a book nook or tablet. This is a small inconvenience, to get such good light, though.  I would buy it again.
