Review: Nice and loud - I was looking for a horn I could use on my power wheelchair. People seem to have their heads in the phones these days, not watching where they are walking. I've had people walk straight into my wheelchair or right across my path. Saying "hey" or "excuse me" doesn't seem to work much. When it does, they always say, "I didn't see you." Of course they didn't, because they weren't paying attention. (I'm surprised there aren't more accidents where people with their faces glued to their phones walk into open manholes or walk into moving traffic.) This horn does the trick. It is loud enough to get them to look up from their phone. It also gets people to get out of the way, instead of standing transfixed by the oncoming wheelchair like a deer in headlights. I wish it had a mode where it played an "ah-oo-gah" sound. That would be a little gentler and more humorous than the current strident "wake up, you blunderbuss" sound it currently plays.
Review: Works great - Very loud! Tested it in the house and it was like an airhorn. Definitely will get attention of anyone outside.
