Review on Classroom Learning Resources: LED Light Buzzers by Walter Velasquez

package arrived quickly. A bit pricey but essential for a Halloween party. Removing the battery compartment was a little tricky, and it was very difficult to remove the battery cover screws to insert AAA batteries. You will need the smallest Phillips screwdriver to open the battery compartment. Think of the size you need to fix your glasses. You need 8 AAA batteries, which is a lot. And there's no volume control on the buzzers. There is also no on/off button. This makes them very easy to remove. It is strongly recommended to remove the batteries to prevent them from being discharged and to avoid accidental loud noises. You have to know that each color has its own sound. Some are more annoying than others. Still worth getting, but wish it had a power button or volume control.
