This is a great little monocular to have just in case. The reason I got it was to have to be able to scope this that my 4x ACOG couldn't do well. It's a tough little monocular because it has riding in my flak for 5 months without a problem. The only downside is the eye relief doesn't let you use it with glasses on and when you try to see things at a distance details are hard to pick out with a small FOV.
Pros: Small, Low Price
Cons: FOV, Eye Relief
