Instructable on Mason Jar Hive, what are your pros and cons on this?

I was looking at http://Instructables.com , the contest area an a individual had created a hive using mason jars, great for viewing but also great for harvesting. What are your thoughts if any? http://www.instructables.com/id/Easy-no-mess-mason-jar-beehive/

Well, it is basically a honey super - not a whole hive. It also seems like a lot of effort making the kit up, while at the same time unduly restricting space to the bees (they get the volume of the jars, not the whole box and it looks impossible/difficult to add additional supers above.

To me it looks like a complex and comparatively expensive gimick. A solution looking for a problem.

Want to see the bees building? Use a viewing window on one side.
Want to harvest cutcomb honey - use a Top Bar Hive.

seems like a fun gift idea or even a gimmick for selling at market.

Actually, Tel is right on that - you could set up a little observation hive using jars to take to market with you. A gimmick really helps drawn in customers, especially if it looks cool. And if they feel entertained they may be more likely to buy from you.
