This ball is beautiful, and really interesting to look at and play with. However, after a day of gentle use, it split completely, and got blue goo all over everything.Update: upon receiving this review, the company reached out to me, offered a full refund, and sent me another product. They also included a small gift. I also received a thank you note in the mail.The customer support on this company is seriously next level, and Im really impressed.In addition, this new ball seems to be a lot sturdier than the first one, and we have had it for over a week with no problems at all.
