Save your money

Bought this when first came out. Seems to be a good product, however shortly after trial period is over all you have is velocity. $150 for ball then they want $10 a month to see everything else. Looking at $270 for this over first year. No thanks. Way too much. Should of stuck with the Skillz balls that read velocity for $20 with no other fees. Other traditional methods for seeing spin. Hopefully competitor comes out and they have to adjust those monthly fees.

Don’t waste your money

Excellent customer service. I have a problem with the first ball I received after two phone calls I had a brand new ball. So far the second ball works flawlessly.
