Installation was simple and it does work. It is as loud as any other buzzers I have heard in my, admittedly, limited experience. Even louder would be nice.

Can't be Beat

These are the best buzzers. Love the fact that they have their own battery. No matter what happens I know I can find my quad. The best peace of mind you can buy for 15$. ViFly is a great company too. Making lots of unique products instead of just cloning others.
