It's crazy people are asking it for free from a small business owner. Looks like this product is another tool to help our DD's understand leg drive and I don't think 269$ is a bad deal. People didn't have problem dropping 300$ for Ghost bats produced by a major manufacturer. If my daughter was 10 YO, I would buy this product, it's a good innovation.
I have no problem purchasing if someone on here recommended it. I thought a fair review of the product would be good for both parties. And offered to pay if it worked.
