I like the fact it is real straight forward puzzle. No real luck involved and you can really think about how it works. Also funny/stupid; Two weeks ago I had some people over and while I was talking I reseted the puzzle, but put the draw in the wrong way,...... Not a big issue, just had to fabric a small tool to re-open it. Well at least my visitors had a good laugh about it and of-course I did as well.

The Washington monument is also a nice puzzle, but to be honest I don't like it that much. I opened it very quickly, but not in the 'correct' way. I know I wasn't the only one. Still a very nice puzzle, but the Plugged Well is in a different league.
On another note when I received both together with the Telephone booth I also got a nice puzzle for free. The SEARious Burr 13 piece burr with secret lock!!

I even prefer this puzzle above the Washington monument.
