Pros: Makes A Great Gift, High Quality Materials, challenging, code for free virtual daily calendar
Cons: no month overview
I have bought this calendar consistently over the last 3-4 years. Mensa puzzle books were always my favorite as a kid and now I get a puzzle each day with this calendar. The puzzles are great, some harder than others, but mostly solvable and others I get stumped. I also like that you get a code in the back of your calendar for any other page-a-day calendar free, sent to your email daily. This last purchase I made through ebay.com, may calendar pages were mounted upside down on the prop backing, but calendars.com exercised great customer service and sent a new calendar out immediately, no questions asked. I was glad that I could have one for my desk and share one with my friend who teaches gifted middle school kids. I'm sure they will enjoy as much as I do!
Pros: Makes A Great Gift, verbal as well as mathematical puzzles
If you enjoy a challenge to begin or end your day, this calendar offers mental exercises within the reach of folks other than the braniac population. Solving the puzzles brings satisfaction and a much needed ego boost.
If you ever need a good idea for something different, this is the perfect gift for the person who has everything. I found it to be an especially nice gift for a man, whether he has a desk job or not, as he will anxiously await seeing his daily puzzler..
