Pipeguard is not BS. Magal actually had a very successful trial with Yukos Oil in Russia. Unfortunatly, when the Russian government froze Yukos assests this halted any implementation of the product. One the Russian Government has taken over Yukos or their problems are resolved the product may well be revisited. It is only a matter of time.
I would not rush to such a judgement about a product which is presumably still being developed through rigorous testing procedures. If it can be shown to work, and to be cost effective, I believe it will be very marketable, indeed. The world is full of valued products which were once dismissed as "BS". Remember the airplane?
