I am wondering what anyone can tell me about Fiber Edge? Does anyone use it? It seems durable but I would like some input, pro or con. We found it for 30 bucks a 20 foot section. I know they make 100' but cant find that. How does the price and durability compare to metal edge and the ever popular but rotten looking plastic roll? It is for my house but we do small installs of rock or mulch and would like to know if this stuff is worth using or not. Thanks.
