Buy it for: A permanent-ish net at home. Fibreglass frame, UV-treated netting and ground pegs, in a 5 m or a 3 m length, so a batter can hit properly without fielding every ball.
Not for: Anyone who needs to pack up after each session, or who is short of flat ground to peg into.
Buy it for: Protecting whoever is running the machine. The L-shape gives cover to stand behind while still feeding through.
Not for: Stopping a full-blooded straight drive — 2.1 m square catches a lot, but it is not a cage.
Buy it for: The same protection in a plain square, free-standing and up in minutes. Choose it over the L-shape when nobody needs to work from behind it.
Not for: Machine operators who need a cut-out to feed through — take the L-shape.
Buy it for: Fielding and throwing drills. Two sizes, a fibreglass frame that springs open, and a carry bag — the cheapest way to add targets to a session.
Not for: Batting. These are targets, not a net to hit into.
