Overview
This Sky reaction ball set includes 6 balls, each about 72mm across and 7.2 ounces, in assorted colors. Reaction balls bounce unpredictably off their multi sided surface, used to train hand eye coordination and reflexes.
A set of 6 gives enough balls for group drills or coaching multiple athletes at once, rather than a single ball for solo practice. The 72mm size and 7.2 ounce weight sit in the typical range for reaction training balls, small enough to grip one handed.

Who it's for
Useful for coaches, trainers or parents running reflex and coordination drills with more than one person at a time, given the set of 6. A single athlete practicing alone would only need one or two balls, so this set offers more than most solo users require.
Strengths and trade-offs
Drawn from this product's published specifications.
- Set of 6 balls suits group or coaching use
- Compact 72mm size fits easily in a hand or bag
- Colors are assorted rather than user selectable
- No named brand recognition beyond the Sky model line
Performance notes
The multi sided shape of a reaction ball sends it bouncing at unpredictable angles, forcing quick hand eye reactions rather than the predictable bounce of a round ball. At 7.2 ounces and 72mm, each ball stays light and small enough for fast catch and release drills.
