Like every other accessory, they have good and bad points. If the majority of your shooting is from a treestand and you average the same height, then they are great and will all usually be on out to 30 - 35 yards. But if you like to switch it up and practice more from the ground and change up yardage. then they have a down side. The only major issue I have ever seen is that you need to make certain they stay clean. If you get dust, or dirt into the swivel portion, they can stick some and you may not notice it. I have also had a issue when we had a big rain and I stayed on stand. Water had gotten into the sight and caused it to hang up a little. But these are kinda minor and rare.
