If I was buying a new sight, I would probably get one of these. I had one of the No-peeps that works the same way as the IQ eye does and I loved it. It very quickly lets you know if you are misaligned. It also eliminates the possibilty of a water drop in your peep sight (if you get rid of your peep as well). It is too bad they are so spendy, but I guess others are as well.
