I bought the 12 room version of this house about 10 years ago.  It has held up extreemly well.  It does take patience and time to assemble, but well worth the effort.  The extension pole which I set in concrete works very well and I have had no problems with the lock on the sections.  I recently moved and intend to set it up again.  As soon as a colony is established I will be buying another of these houses or adding more floors to the one I have.
