Review on 🎉 Enhance Your Marble Genius Experience: Sounds and Lights Accessory by Mariqn Carey

Once you master some great configurations these sound modules are a fun addition. I just got Wacky Sounds. You get 2 in a pack and the sounds are random so you get different effects as the balls pass along with the flashing lights. Since the battery life is very short, I assume that the batteries should last a long time. It's very easy to determine if you're building a run from scratch or just replacing an existing part with a sound module. I hope the Marble Genius guys will release more unique addons!
