Highlighted = better of two published figures where "more" or "cheaper" is clearly better. Velocity is not highlighted: faster is not better for every group.

What actually differs

  • SplatRBall SRB400-SUB claims 200 fps against 150 fps for the Nerf Pro Gelfire Uproar, about 33% faster on paper. Faster shots fly flatter and sting more; for younger or mixed-age players the slower blaster is usually the better host's choice.
  • Ammo runs $0.75 per 1,000 for the SplatRBall SRB400-SUB and $0.90 for the Nerf Pro Gelfire Uproar, based on each brand's own refill pack. Over 10,000 rounds of play that is $7.50 versus $9.00.

Which one to get

  • Nerf Pro Gelfire Uproar: A first gel blaster that ships with a big ammo supply Watch out: Runs on 8 alkaline batteries (not included); Hasbro's own copy says AA in one place and AAA in another, so check the box.
  • SplatRBall SRB400-SUB: Teens building a two-team game with rechargeable gear Watch out: Battery runtime is not published, and no range figure is published, so we leave range blank.

Still deciding? Tick both in the spec table to add a third blaster, or work out ammo for a whole game in the ammo and budget calculator. Everyone in range wears eye protection, whatever you pick: see the age and safety guide.
