I had the typical symptoms associated with cyclists falling asleep, tingling, surge-like hands, which was attributable to an insufficient damping the handles. At first I had BBB handles with ergonomic shape trying but they were qualitatively highly questionable, so I have decided on the Ergon grips and do not regret it. Installation super easy and with the fixing screw everything holds bombproof. You notice the difference when gripping the same. I am mountain bikers, so accustomed also ruppiges terrain and by the ergonomic shape and good damping is equal to another, and especially feel safer while driving. I can really recommend this handles just anyone who wants his arms and hands to do something good.
