imagitarium powerheads: any good?

I'm worried mainly about heavy metals leaching into my water. It will just be for salt mixing. I have one for a quarantine tank that's made in Italy, so I'm guessing their OK. Any thoughts? Thanks.

They work but they arent the best looking. If you're just using it for mixing salt thats fine
