I have a GTL 21...positive click at the bottom, not the "dimmer" model. I like it ! It's not the prettiest or the most expensive or even the coolest on the block, but it does work.
To remove and replace it holds the setting just fine at laser distances. I have mine set about 10 yards, it goes right back to center after a remove/replace.
Battery life is good. Keep an eye out at Optics Planet, sometimes they will run a coupon for 10 or 20 % off and free shipping.
I do what the voices in my wife's head tell me to do!
