Review on Kinetic Spring Sculpture: Flow Ring by Billy Berry

My 10 year old grandson was thrilled when he got this! I was out of town and wanted to give him a gift, I saw this and it looked like he liked it and damn he did! He was so excited to bring it to school today I didn't know about it but they studied kinetic energy in his science class and it was a great subject for kids to really experience kinetic energy in a fun way. Also, it was cheaper on your site than some others, which was great for me as I have a steady income. Cannot say anything bad about this product or offer!
