This Rockwool set left a lot to be desired from the moment I opened the package. Even though it came inside another bag, there was loose fuzz and powdery material all over, it just felt messy and not well processed. I’ve used other Rockwool products before and I know a bit of residue is normal, but this one was on another level.It didn’t give me a lot of confidence in the quality. For almost $20, I expected something cleaner and more stable. Personally, I’d rather pay a little more for fewer plugs if it means getting a product that feels more reliable and doesn’t create such a mess.
