How do you get the battery compartment open? I pressed the clip at the end but nothing happens.

Dear Customer, You can see that there is a notch on the cover on the back of the electronic whistle. From here, use your fingers to push the cover of the battery. I hope it can help you. Best, UNIWA Customer Service Team

Does this whistle have a tendency to stop working like the Windsor whistle?

I've never had any issues with my whistle to stop working. It's always working when I turn it on. Has a good, loud sound. Use mine all the time for soccer games.

Is this whistle sound button sensitive?

Dear Cutomer, Please be assured that the electronic whistle has a switch button, if you stop using it, you can choose off. Best, UNIWA Customer Service Team
