Review on Enhance Your Volleyball Skills with Regius Volleyball Training Equipment 3.0 - Premium Solo Trainer, Ideal for Beginners Mastering Serving, Setting, and Spiking; Perfect Gift for Volleyball Enthusiasts! by Brian Malith

Ordered this for my teenager so he can exercise on his own. The ball mount seems to be working well so far and will come in handy. However, very disappointed that only one assembly line arrived. That means she can't practice tuning like this product is advertised, so I overpaid for what we got - a ball cord and (useless) adjustment strap. Unfortunately my daughter had already thrown away the packaging by the time we noticed this so we were unable to return it.
