HEAD RESET 4 pelotas de tenis

I use them here in Nairobi 1800 meters high, i play on hard and on clay that in nairobi is called murram, with a lot of small stones it really consumes balls, but these they can be used for well over 14 hours, i have never seen the like. i play daily 2 hours or more. should i mention they also come ...

Only just discovered these and am really impressed. As Head say they’re perfect for coaching and my own regular doubles. Only annoying bit is the box is too flimsy. The plastic waste in regular balls is awful.
