With some care & maintenance, your HECS Balls will last you a very long time. Just remember two things:
1. Go Easy
HECS is about hand-eye coordination, not power. Hit in a controlled manner – save the smashes for shuttles on the court – and your HECS Balls will thank you. If the ball flies twenty feet, you’re hitting too hard.
2. Get Out Your Scissors
This part might bug you a bit. A HECS Ball has thousands of exposed yarn filaments, the more frayed the better as they matt together. However, some of these will wiggle and stretch apart, and you’ll notice them poking up. These should be nipped with scissors. Resist the urge to just pull the whole thing out; they are there for a reason. This is to be expected, especially during the initial break-in period (the first hour). And as you go, you’ll find this happens less and less.
