Each Talking Brix 2 can record up to 10 seconds of audio; these messages can be used for reminders, organizational assistance, and more. The small size allows them to be carried in a pocket, purse, or placed around the home or office. Each Brix comes in a bright color (green, blue, or red) for easy differentiation, and includes its own clear snap-cap that can be used for attaching an identifying image, symbol, or word as well. A recording lock helps prevent users from accidentally erasing messages. Dual amplifying speakers ensure messages are clear and easy to comprehend. The built-in batteries are long-lasting and rechargeable for years of reliable use.
