It's not bad for the shrimp. I use it in my tank for 7-8 months now.
It's a PITA for plant management as it's light, it's good for carpet plants because they can root it quickly but once you need to trim and replant it will make you pull your hair out.
In my shrimp tank I use it with an UGF and that seems to keep it in place. I think it depends on what you plan on using it for.
