Was looking for one of these to help with seeing the paper holes and didn't want to spend big $ on something I don't use often. Optics are very clear for an inexpensive piece of glass. Very lightweight, portable and easy to set up. No problem seeing the .22 cal. holes @ 200 yds. On the downside, eye relief is terrible. Need to get right up on the eyepiece. Low light gathering ability is also poor. If this is to be an integral part of the equipment bag, buy something better. If using it primarily for sighting-in, it will do fine. Overall, I got what I paid for.
Pros: Clear optics
Cons: Eye relief
