me and my buddies have been playin with them a couple days for quit some time and they still are bright as ever and work great! but the real test will be next weekend at aphrodesiac and idc what you think because for some pocket change these things are bad ass! they dont have different modes but for me strobe is good enough for 79 cents rather than pay a couple bucks for a one colored LED light that just stays on even though i like those too! But ill let you all know how they work when actual ravin is applied
