Got the book as a birthday present. Very dissapointed that it's only 40 pages. I thought it was around 150 pages and way overpriced. There are better books on the market. If you can't find a well reviewed one pass this one. I'm trying to return for refund. Really feel scammed. Thanks Amazon. :/

Ex Output:
Bad review

Ex Input:
I don't know what to write here, this product didn't work at all for me. It was a complete waste of time and money. I tried it on one eye first, the light did not affect my eyeglass frame or any other part of my body whatsoever. To conclude just dont buy. I will probably never be able to find something else that works. Save your money - there are plenty others out there. I wouldn't suggest giving this little cheap thing even 1 star but you have to.

The only thing I want from a light is the ability to turn it off. This little lamp does that. I've had one now for nearly 7 years - still working fine. Pros: Extremely adjustable: There are no hot or cold. It's on all of time. In fact, there's probably one setting that would make me too lazy (doesn't matter which setting) and set at minimum brightness.
