I haven't tried the voice changer yet as it didn't come with batteries??? Really... thought for 80 bucks it should have.
I'm not too impressed by it. I mean it is ok, fits pretty good. The inside straps don't do much I feel. I was very excited when I ordered it, it displays well... good for cosplay, but this is a Rogue One bucket which can't be compared to any other Stormy helmet so I'll keep it.
