Works great, the app allows extra options like changing the lighting with an RGB slider, making the sword SFX come out of your phone instead of the low volume built-in speaker in the sword, grip sensitivity change, and static light mode where the lights stay on with no sound effects for displaying/cosplaying purposes. It would be nice if the static light mode would have the option to play sword swing SFX too though and not just sword impact SFX. A downside to having the SFX come from your phone is that the app MUST always be open. If you lock, switch apps, or close the app, the sword gets locked into phone output and you must restart the app and switch it back to get the sound working again.
