Yes, it is easy to use and worthy should you travel long distances, overland or across Europe. IMO the best (or safest) way to use it not to completely lock the throttle but to let it slowly unwind when you let go the handle bar. However on long motorway stretches you can lock the throttle and let it do the job by itself. The thing is that the thread of the "lock nut" is reversed and works for releasing the locked throttle whenever you need by just turning back the twist to release. Handy. Many ways to use it. The whole thing weighs around 200 grams which is pretty good bar end by itself
