Don't just take my word for it, put up a target on a range at night and then stand back at about 7 to 10 yards and line up on the target. The really bright dots like Mepro will drown out the target. It can happen with most 3 dot sights in fact. I think you're really better off with either a front sight only Trijicon insert, or a 2-dot sight.
Most folks don't get the opportunity to shoot at night due to range restrictions, but you owe it to yourself to do so somehow.
