I already owned the acoustic loog mini from their first kickstarter many years ago, and when I saw that ToyCycle had the electric mini at used prices, I just had to get one to see the difference (between electric strings and acoustic strings). I'm so glad I did! The new generation of loogs has updated cards. My original first gen are still great, but I appreciate the bigger new cards. I also really like the electric loog mini. It's fun to play around with the sound, and I love how the amp is built in. My husband enjoyed playing a rock version of Itsy Bitsy Spider for our toddler, who enjoys strumming on both the acoustic and electric loog minis.
