The Ratso's don't glow at as much as some other lures,a few minutes is all you get,when glow lures are working,I tazer they on every drop.I put all my glow lures in one box,and looked at them in the dark,the glow red lures seemed to glow the brighter and longer.I will say THE RATSO'S is a great lure,it's one of my go too lures,I've been using two lures this year,a clean chartreuse Ratso's and a firetiger Gill Pill,tipped with a wax worm,in two days 64 Bulls 8-9 1/2 inches have made there last mistake.
