Learn what you need to know before buying refills for the Ball Launcher Dispenser from CrunchLabs. This guide covers compatibility, sourcing, and practical tips.

Quick answer

The Ball Launcher Dispenser is designed to work with standard-sized plastic balls, but not all refills are equal. Stick to balls that match the original diameter and weight to avoid jams or poor performance.

Why ball size and weight matter for your dispenser

The Ball Launcher Dispenser relies on a precise mechanism to feed and launch balls one at a time. If you use balls that are too large, they may jam the feed ramp. Too small, and the launcher may not grip them properly, reducing distance or causing misfires. Weight also affects trajectory and the wear on the spring or motor.

Where to find compatible refills

CrunchLabs does not currently sell an official refill pack for the Ball Launcher Dispenser. That means you'll need to source balls from third-party sellers. Look for plastic balls with a diameter of approximately 1 inch (25 mm) and a weight similar to a standard ping-pong ball. Avoid foam or lightweight balls, as they may not trigger the launcher mechanism reliably.

Your decision rules for ball launcher refills

  • Diameter check: Measure the balls you plan to buy. They should be close to 1 inch (25 mm). Anything larger than 1.1 inches or smaller than 0.9 inches may cause jams or poor launching.
  • Weight test: Weigh a sample ball. It should be roughly 2.5 to 3 grams. Lighter balls may not engage the launcher, while heavier ones could strain the mechanism.
  • Material preference: Choose solid plastic balls, not foam or hollow rubber. Foam balls compress and can get stuck. Solid plastic provides consistent performance and durability. Avoid foam or hollow balls; they are the most common cause of jams.
