Been using Airzound airhorns for 20 years now (with a bell for close-in pedestrians). I now have three bikes, two drop bars and one straight. I mounted the Airzound's thumb button by my left hand on each bike, with the bell in a similar position on the right. On the new Charge Plug I ride on the hood of the brifters and I positioned the horn so I honk it with the three small fingers of my left hand. The bell with the thumb of my right (from the hood). On my Nishiki International road bike I'm mostly on the top bar when in traffic so the horn button and bell are under my thumbs. And on my Nishiki Blazer straight bar the horn and bell are under my thumbs as they rest on the cross-fire shifters. After a few days of noisy practice I got used to the new position and didn't have to think about it. The same with the brifters, vs, cross-fire, vs downtubes. It's like driving two or more vehicles regularly, you get used to the position of the controls. granted the horns are usually in the center of the wheels...but there was that '77 Ford Fairmont with the horn on the left stalk. And that was my first car where the switch for the brights wasn't on the floor. And oh, yeah, one car had a column shifter, one had an automatic on the center console and one had a manual on the floor. You get used to things. The only drawback to the Airzound is around freezing and below where it becomes less effective, but the new one has a metal bottle pumped up to 100psi and it seemed to get a couple of good loud blasts in the lower 20s. I think the Airzound elicits a better response than the electronic buzzers and chirpers I had before since it is a horn sound. These horns have saved my life from inattentive drivers a few times, and come in handy to warn other drivers before they get too close for comfort. I love, Love, LOVE them.
