I purchased the Spot Rebounder 7 x 7 as I am relearning to play tennis righthanded. It arrived promptly however the installation instructions are minimal and generic and I found it impossible to tension the net, snapping a pole in the process. The complaints team were excellent sending a replacement swiftly. I can only erect by using the green bungees that are supplied but with no explanation of use. The pace and trajectory varies depending on where it hits the net but as control and consistency is what I am trying to improve it works for me. The high score is due to the complaint response.
