there warantee is great! I had one of the strikefire redots that was a red/green combo model and it just wasnt bright enough in sunlight and i called them and they said to send it in and they would send me the new just red model for free and it was a brighter dot. I did and it sure was. Those strikefires are a real bargin in a redot. Mine have held up as well as my aimpoints at 1/4 the cost. Only downside to them is battery life isnt as good as an aimpoint but that been said the same batterys have been in mine for over a year. You just cant leave them on all the time like an aimpoint. As a matter of fact they have a automatic timed turn off just in case you forget. Thats fine for a 22 like mines on but i wouldnt want to know that my sight on my ar will turn off when i least expect it. If my strikefire and vortex binoculars are any example you wont find better optics for the money anywhere.
