I have tried all the stick on things but still get impacts,the vertical blinds
in any position are no deterrent.I have looked hard at the patio door and
cannot figure out what it is they see,the door is shaded by a porch so
there is not much of a garden reflection
Perhaps a reflection would show their own image closing at speed and deter
them,with the amount of glass in modern buildings a fool proof solution must
be worth money!
So to sum up thats a "don't know"
