What owners report

Convoy S2+

  • ✓Enormous emitter and tint selection — you configure the light rather than accept a default
  • ✓$15 to $20 buys build quality reviewers rate alongside brands charging five times more
  • ✓Simple, reliable driver options with no firmware to go wrong
  • ✓A decade of production means accessories, hosts and modding parts are everywhere
