I have the I-40 & the I-60. Battery life is very, very good. Trigger speed is very good as well. Depending on where the camera is placed ( shade vs. sun ) you will get whiteout AND daytime IR pics. The more sunlight there is on the cams, the more colored pics you get. The colored pics are very good. I really like the nightime IR pics as well. They're crisp & the IR emiters really put out the light. Go to www.Chasingame.com reivews & forums to gather more info.
