We bought the balls - which are really tennis training balls - in a bid to mollify neighbours who complained incessantly about the noise of the standard balls. The group consensus was the silent balls played so differently they were unusable. Kudos just the same to staff at the shop for their time answering our questions
Excellent product - highly recommended!
Yes received the balls in a timely manner and have been using one down in my basement! Taped net and kitchen lines and have been practising...at least a little exercise dinking
