Haven't gotten to use them yet.  Looking forward to it.                                                                                Now May 2nd, 2022.  I constructed a Tiki type outdoor room and get many compliments on it.  It has been up a year now, and withstood winds up to 50 miles an hour.  The only thing I can see, but didn't know is that the Bamboo dries up quite a bit and is getting brittle.  I love my Tiki room!
