Review on 🚲 Accolmile Electric Bike Horn with Anti-Theft Motion Sensor Alarm and Remote Controller | Waterproof Bell for Mountain Bike, Scooter, Road Bike | USB Rechargeable Ebike Bell | Loud Sound Ring Bell by Bishop Roshad

I bought 3 of these from your Amazon site. I liked the first one I bought so much that I ordered another one for my wife's bike. After the second ride together on our bikes, the horn on my bike didn't work again. even after a full charge. I ride my bike more often, so I took a new one off her bike and put it on mine. Then I ordered a new horn for her bike. When it arrived I fully charged it. Then I used the keychain to check. It worked fine. A few days later I wanted to install it on my bike and now it doesn't work. Are they really defective or am I doing something wrong? I tried to return it but Amazon says it's non-returnable. I am not satisfied and am afraid to order more.
