Review on 🎾 Enhance Your Tennis Swing with the Oncourt Offcourt Tennis Grip Trainer Swing Tool (Multi-Packs) - Start Rite Swinging Training Aid Equipment by Dylan Deng

Works well. This is a good tool to teach specific holds without the hassle of explaining. My student used to have trouble hitting with a one-handed backhand, but he hit flawlessly with this tool. Even teaching the continental grip for volleys and serves works well. Cons: It tends to be uncomfortable on hands and they need to be secured with velcro as it won't stick for long after hours of use. I ordered 6 pieces but only 4 were delivered.
