I bought one of these for myself and a few others for friends...
It's difficult to fault the images and the paper is much better than the flimsy Lonely Planet Calendar I heard for 2010.
So what's the problem? The hooks are AWFUL!
The hook was only designed to hang the calendar to only view the cover page. To actually see a particular month, you will have to rely on a tiny hole and (probably)some sellotape by the time you get to February or March.
Having said that...
I only paid about £4 and for that price (bearing in mind the design flaw) I can live with it. Had I paid the cover price (£12ish), I would be very angry!!!
I'm not sure if this is a 'fault' that is common to similar square grid calendars by the manufacturer. I hope not!
