I ordered one of these as when reading late in the evening was getting fed up of the 'when are you turning that light off so I can get some sleep'. Husband even suggested I got a book light, so did some searching and choose this one.
The reasons were: It comes complete with batteries already, it has a nice slim design, doesn't look too heavy for reading even with paperbacks and all the positive comments already on the web.
It does live up to it's expectations ... but when you open the battery compartment do be careful, the little round batteries have a tendency to leap out at you, so just watch the plastic strip when removing best done over a table or worktop with no animals or toddlers around.
The light it emits is very bright and with it being able to rotate there is no need for anyone to be troubled by your light, which means I get to read in bed whenever I like without being moaned at, so a positive well, 5 stars for me for this product. Feels well made for such a tiny item, the one thing I did have a problem with at first was finding the on/off switch (try being half asleep and trying to find it without waking your other half by shining the light in their eyes, well, it was an accident).
The batteries it requires are not that expensive (take a look when ordering the book light, I did and they were really cheap with free postage with one seller) worth getting when on offer to put away for when your batteries run out.
There are a choice of colours from the bright girlie pink which I choose to grey of for those that prefer more formal/male colours, so really a colour for everyone that likes their books.
