Has anyone used these? Do they increase speed and reduce noise?

Supposeddly they do the same as speed nocks. Placed strategically on the string near the cams they can cut down on some string oscillation and increase the speed of the bow. However, to get them in the right place requires a chronograph and some trial and error to find that sweet location.
With speed nocks not only is location important, but how many you use. IMO the Speed Demons are a gimick.

Gives an average of an extra 5-7fps arrow speed.

A new device to dampen oscillations of the bowstring, resulting in more energy being transmitted to the arrow.

Speed Demons increase arrow speed by 5-7fps & dampen string vibration. See Speed Demon installed on a bow string below.

When properly installed on your bowstring, these innovative "demons" will increase arrow speed 5-7 fps and dampen string vibration.

Lol! If that was correct all the bows would have them as standard and everyone here would use them too. ;)
