Three week summary- Returned to amazon. Good customer service but poor overall product. The actual board is nice. But the ball is the most important part and it’s cheap.
I was able to progress quickly and pump the ball up to 8psi after the first week, while using on hardwood floors. It was very fun and I could balance for 5 minutes relatively easy. Then the board became very unpredictable and I found the ball was warped with flat spots. After a few frustrating falls I left a 3 star review on their website mentioning the ball (although it seems they hid my review). Customer service reached out and immediately shipped a new ball.
Great. I decided I would use the second ball on thick carpet to see if it would last longer. The first day was awesome and very stable. But again the ball warped and was unpredictable after only 1 week. It’s dangerous and not fun when you’re only balancing to avoid a fall.
I’m 180lbs. I think this product is for someone who wants to use it once a month, or if you weigh <130lbs.
