I’ve used both the Domino and the JetPrime quick turn throttles, my Domino was fine until it failed on me. Switched to JetPrime when I replaced it, the JetPrime seems to have a higher quality of manufacture, same throw as the Domino but the whole unit feels more solid with a crisper snap back than the Domino. Not a big enough difference to change to Domino to a JetPrime unit if you already have a Domino, but if you are buying a new throttle anyway the JetPrime seems the better option.
