I had a couple of their silk plants, and a couple of the softer plastic ones for my boy. During my recent cleaning, I noticed what looked like a stain on the glass bottom of the tank. Realizing it wasn't just waste, or coming off easily. I pick up the plant and look at the base. It was RUSTING. Their bases contain some sort of metal. Beware!
That's not the only thing.... When I had those in my tanks with mollies the ends of the leafs frayed. What ended up happening was the mollies swallowed the threads...they must have blocked up their digestive systems because they all started to drop like flies. I of course thought this was some sort of internal parasite because the threads protruded halfway out of them. I had started to treat with some heavy medications which ended up stressing and killing the rest of the Mollie. Point being natural is better... Natural plants absorb ammonia and other by products, provide shelter for fry or bullied fish, or even look nicer and more vibrant. I think these plants are modeled after real amazon swords *I think thats the common name* and I have seen them in green but they might exist in red I just haven't seen it.
