Has kept the deer off my hostas.  It is a bit trickey to install it easily tangles.  A fledgling robin got cought in it.  foot went through the opening.  it eventually got free.  The mesh seems strong enough it catches small sticks that fall from nearby trees.  Not sure why the deer leave it alone, but it seems to work.  I'll try it on Rhododendrons, hydragea, lillys, holly comre winter.,
