Many people ask what is the difference between Hasbro Stormtrooper Helmets and Anovos and eFX. Hasbro Helmets are nice. You can get them for $100 or less. They do have the voice changing device inside them. On the down side they aren’t as good quality as Anovos or eFX. If you are buying for a kid to play with I would recommend the Hasbro. The Anovos helmet is highly detailed top quality replica that can be worn. It doesn’t have a voice changer. The eFX as well is a highly detailed top quality helmet but it is more for display. This helmet can be worn but isn’t recommended. It has padding in the helmet so it isn’t uncomfortable to wear but it doesn’t have the adjustable head band like the Anovos has.
