It's loud enough and easy to attach.works well

### ⭐⭐⭐⭐⭐ It Works!
*by R***N on December 5, 2020*

I'm an avid cyclist who believes in the laws of physics, so I try to alert pedestrians, dogs, and cyclists, when I'm planning to pass. Unfortunately getting people's attention on busy bike + pedestrian trails, and city streets, has always been a challenge. Cute bells, clown horns, and shouting, all failed to do that. Then I got the Ytuomzi!Even though 20% of pedestrians will never hear it over their earbuds, phones, and random distractions, and another 10% think the antique car horn and siren sounds are birds (I swear they ALL say that!), I appreciate the loud volume and cool sounds this little device emits. The sounds are loud and just obnoxious enough to get most people's attention. Best of all is how popular the antique car horn is. Little kids love it. Dogs respect it. People my old age dig it. Mom's chuckle at it. So it works!I've also used it on 1 charge for over 3 weeks, in rain and 40 degree F temperatures, and on busy roadways, without a hitch. It really holds a charge. I like it so much after 2 months of use I bought 2 more as Festivus presents for my family members who also ride bikes. It's a good quality horn at a great price.
